Introduction

Getting Started

Once you have created a frame of parts in your Tekla Structures model, you will need to connect those parts to complete the model. Tekla Structures contains a wide range of components that you can use to automate the process of creating a model. This chapter explains the basics about components - what they are and how to create them using Tekla Structures. We will begin with the basic concepts, followed by a general description of components properties. Finally, we will show you how to use components in practice.

Contents

This chapter is divided into the following topics:

• • • • • • • • •

Basics of components (p. 9) Component catalog (p. 17) Using components (p. 23) Defining parts and plates (p. 29) Defining bolts and welds (p. 33) AutoConnection (p. 42) AutoDefaults (p. 45) Using the joints.def file (p. 46) Using Excel in connection design (p. 58)

1.1 Basics of components Introduction

Components are tools that you can use to automatically create the parts, welds, and bolts required to connect parts. They are linked to main parts, so, when you modify a main part, the associated component also changes.

Benefits

The main benefits of working with components are: 1.

2.

You can save the properties of a component using an easily-identifiable name and keep it for future use. For example, you could save the properties of a W12x65 column base plate connection as W12x65.j*, and use it for several projects. When you modify the size of a profile, Tekla Structures automatically modifies the relevant components.

TEKLA STRUCTURES 17 Getting Started

3. Topics

When you copy or move objects, Tekla Structures automatically includes all the associated components.

Component concepts (p. 10) Component catalog (p. 17) Component dialog box (p. 11) Selection order (p. 13) Up direction (p. 13) Automatic and default properties (p. 14) General tab (p. 15) Design and Design type tabs (p. 16)

Component concepts Components are tools that automate tasks and group objects so that Tekla Structures treats

them as a single unit. Components adapt to changes in the model, so that Tekla Structures automatically modifies a component if you modify the parts it connects. This is an example of how to apply a connection:

Select the main part. Select the secondary part. To see information about the connection, click the connection symbol. The connection automatically creates the required parts, fittings, bolts, etc. Component types

10

Components have the following subtypes:


Componen t type Connection

Detail

Modeling tool

System and custom components

Description

Examples

Symbol

Connects two or more parts, and creates all the required objects such as cuts, fittings, parts, bolts, and welds.

Two-sided clip angle, bolted gusset.

Adds a detail or a reinforcement to a main part. A detail is only connected to one part. When you create a detail, Tekla Structures prompts you to select a part, followed by a point to locate the detail.

Stiffeners, base plates, lifting hooks

Automatically creates and assembles the parts to build a structure, but does not connect the structure to existing parts. Modeling tools can include connections and details.

Stairs, frames, towers

Corbel connection (14)

Beam reinforcement, pad footing reinforcement

Tekla Structures contains hundreds of system components by default. You can also create your own components, custom components. They have following subtypes:

• • • •

connection detail part seam

All components are stored in the Component catalog (p. 17). To open the component catalog, use the keyboard shortcut Ctrl + F. See also

Custom Components (p. 65) Exploding components (p. 66)

Component dialog box The component dialog box is in two sections. Upper part

Use the upper section of the dialog box to save and load predefined settings. For more information, see Save, Load, Save as buttons. For some components the upper section also contains buttons for accessing the bolt, weld and DSTV dialog boxes. For information on handling the saved properties, see Connection properties files.


11

Tabs Tekla Structures uses the automatic property value The parts the component creates appear in yellow The green symbol indicates the correct direction for the connection or detail. The parts you select appear in blue. Tekla Structures uses the default property value Lower part

The lower section of the dialog box is divided into tabs. This is where you define the properties of the parts and bolts that the component creates. The most common tabs that appear here are:

•

Picture illustrates the component. It shows just one example, but you can usually use one

• •

Parts is where you define the properties of the parts the component creates

component in many situations.

• •

Parameters is where you set parameters to control the component (for example, for stiffeners, end plates, chamfers, etc.) Bolts is where you define the number of bolts and their edge distances General is where you define the direction of the connection or detail and AutoDefaults

rules

Selection order To create a connection you need to select or pick existing parts or points. The default selection order for a connection is: 1. 2. 3.

Main part Secondary part(s) If there is more than one secondary part, click the middle mouse button to finish selecting parts and create the connection.

Some connection dialog boxes illustrate the selection order for parts using numbers, as shown below. Select the parts in the order shown in the picture:

Details

The default selection order for a detail is: 1. 2.

Modeling tools

Main part. A point in the main part to show the location of the detail.

The default picking order for a modeling tool is: 1.

Pick one to three point(s) to show the location of the objects the modeling tool creates.

Up direction The up direction of a connection or a detail indicates how the connection is rotated around the secondary part, relative to the current work plane. If there are no secondary parts, Tekla Structures rotates the connection around the main part. The options are: +x, -x, +y, -y, +z, -z. The Picture tab in the dialog box shows the up direction Tekla Structures will use. Tekla Structures also indicates the up direction in the connection symbol:


13

Manually defining up direction

To manually define the up direction: 1. 2. 3.

Double-click the connection symbol to open the connection dialog box. On the General tab, change the x, y, or z direction. Try positive directions first. Click Modify to use the new values.

Automatic and default properties Some connection dialog boxes contain list boxes that show property options as graphics. You can select system defaults, AutoDefaults, or have Tekla Structures automatically set the properties. System default properties

14

If you leave fields in connection dialog boxes blank, Tekla Structures uses the system default properties. Manual entries, default, automatic and properties in the joints.def file, all override these system defaults. You cannot change system default properties.


Default and automatic properties

Icon

Description

More information

To have Tekla Structures use a default property in a connection, select the option marked with this symbol.

Using AutoDefaults (p. 45)

If you use AutoDefaults for the connection, Tekla Structures uses the property defined in the AutoDefaults rules. If you are not using AutoDefaults, Tekla Structures creates the connection using the system default property. If AutoDefaults have been used, the actual picture in the default option does not necessairly match the outcome. To have Tekla Structures automatically determine which option to use for a property, select the option marked with this symbol. Example, Boomerang bracing connection (60):

Use the Automatic option on the Gussetbolt1 tab to have Tekla

Structures determine how the clip angle is connected to the gusset plate and beam. See also

Using the joints.def file (p. 46)

General tab Connections and details have the same General tab. It contains the following properties:


15

Field

Description

More information

Up direction

Rotates the connection around the secondary part or detail around the main part.

Up direction (p. 13)

The fields next to the image define rotation angle around the x- and y-axis of the secondary. The upper one is for y- and the lower one for x. Position in relation to primary part

Available only for details. Select a checkbox next to the images to indicate the position of the definition point of the detail, relative to the main part. Use the Horizontal offset and Vertical offset fields to define the horizontal and vertical alignment of the detail, relative to the main part.

Locked

Prevents modifications.

Locking objects

Class

A number given to all parts the connection creates. You can use class to define the color of parts in the model.

Color settings for parts

Connection code

Identifies the connection. Tekla Structures can display this connection code in connection marks in drawings.

AutoDefaults Rule Group

Automatically sets connection properties according to the selected rule group. To switch AutoDefaults off, select the rule group None.

AutoConnectio n Rule Group

Automatically switches the connection to another according to the selected rule group.


Design and Design type tabs Some component dialog boxes include a Design tab, others include a Design type tab. Use the options on these pages to check if the component will bear the UDL (uniform distributed load), according to AISC (ASD) specifications. This design check is intended for use with imperial units. The Design tab also contains options to:

•

Use AutoDefaults rule groups to automatically modify component properties to take the calculated load. To define which AutoDefaults rule group to use, go to the General tab and select the rule in the AutoDefaults rule group list box. For more information, see Reaction forces and UDL.

16


•

Design tab

Use information in an Excel spreadsheet to check connection design and automatically update component properties to bear the UDL. This is useful when you want to check connection design according to other design codes. See Using Excel in connection design (p. 58).

To check the design of a component that has a Design tab page: 1. 2. 3. 4.

Go to the Design tab and select Yes in the Use UDL listbox. To use information in an Excel spreadsheet in the UDL calculation, select Excel in the External design listbox. Enter the information you want to use in the calculation in the remaining fields. Select a connection in the model and click Modify. To view the results of the check, rightclick the component symbol and select Inquire from the pop-up menu.The inquire object window opens, which contains a summary of the design checks and related information.

See also Using Excel in connection design (p. 58). Design type tab

To check the design of a component that has a Design type tab page: 1. 2. 3. 4. 5. 6.

Open the component properties dialog box. Go to the Design type tab and select Yes in the Check connection list box. Tekla Structures will check the connection each time it is used or changed in a model. Enter the information you want to use in the calculation in the remaining fields. Select a connection in the model and click Modify. Tekla Structures checks the component. A green component symbol indicates that the connection will bear the UDL, red indicates it will not. To view the results of the check, right-click the component symbol and select Inquire from the pop-up menu.The inquire object window opens, which contains a summary of the design checks and related information, for example:

Primary angle, Gross shear [AISC ASD F4-1 (p5-49)] applied = 250.00, allowable = 190.80, capacity = 1.31 FAIL (t = 0.5000, tmin = 0.6551) Example of design check information in the Inquire object dialog box.

• • •

The first row shows the part checked, the name of the check and a reference to the AISC specification. The second row shows the applied and allowed force and how much capacity has been used. The third row shows the results and possible solutions. In this example the primary angle plate was not thick enough. Tekla Structures has indicated the minimum thickness required to bear the UDL.

1.2 Component catalog Tekla Structures contains a component catalog, where all components and sketched cross sections are stored. See also Sketched cross sections. To open the component catalog, use the keyboard shortcut Ctrl + F, or click the Search component icon on the component toolbar (see Component catalog example (p. 18)). Topics

Thumbnail images Most system components have a default thumbnail image in the component catalog, which shows you a typical situation where the component can be used. For example, this is what the thumbnail image for Bolted gusset (11) connection looks like:

To edit a thumbnail image for a component: 1.

Create an image and save it in bmp format in ..\Tekla Structures\\nt\bitmaps folder. To create the image, you can use Create View > Default Views of Component and Screenshot commands, for example.

2. 3. 4. 5. 6.

Press Ctrl + F to open the component catalog. Right-click the component and select Change picture... Locate the thumbnail and select it. Click OK. Tekla Structures links the thumbnail to the component.

Descriptions and keywords Descriptions

To view a component description, select the component in the Component catalog. Use the

button to show or hide descriptions.

You can create new descriptions and edit existing ones:

• • • Keywords

The default component descriptions are stored in the xslib.db1 file, located in the model folder. To add or edit a description, type text in the description field. When you select another component in the component catalog, Tekla Structures prompts you to save the description you added or edited. After you have saved the description, save the model also. Edited component descriptions are model-specific.

To add or edit keywords, right-click a component in the component catalog, and select Edit keywords...

Keywords you add or edit are saved in ComponentCatalog.txt file in the current model folder. You can combine ComponentCatalog.txt files and move them to the system folder:..\Tekla Structures\\environments\\system.


21

Grouping components To create a new folder based on the results of a search:

1. 2. 3. 4. Removing components from groups

In the Component catalog, enter your search criteria and click Search. To group the search results in a new folder, click Store. In the Store search result dialog box, enter a name for the folder and click OK. The new folder appears in the tree.

To remove components from a group, right-click the component and select:

•

Remove, if it is a default group.

or

•

Remove from search result if the folder was created from a search.

Copying components to another folder To copy components from one folder to another: 1. 2. 3. 4. 5.

In the component catalog, click the Folders icon to open the Folders view. Go to the folder where the component to be copied is located. Select the component, right-click and select Copy. Go to the folder where you want to copy the component. Right-click and select Paste. If the copying does not succeed for some reason, store the component temporarily to a new folder. 1. 2. 3.

Click the Search icon and search for the component to be copied. Select the component and click Store to create a new folder for the component. In the Folders view, go to the new folder and copy the component from there to the desired folder.

Customizing and saving components Many components are suitable for use in different situations. You can define the properties of a component to use in a specific situation, then save a copy in the component catalog to use in similar situations. For example, we’ll use the Bolted gusset (11) component to connect a single brace at the base plate of column.

22


1.

To save a copy of the component, we’ll right-click the component symbol in the model, and select Publish in catalog.... The Publish in catalog dialog box appears.

2.

We can add the component to a specific group. By default, the component is added to the All group. By default the component uses the same thumbnail image as the original component. To change the thumbnail, see Thumbnail images (p. 21).

1.3 Using components Introduction

This section explains how to use components. It also includes examples.

Topics

Creating components (p. 24) Example: Adding an end plate (p. 24) Example: Adding a base plate and anchor rods (p. 25) Example: Adding a beam to column connection (p. 26) Viewing components (p. 27) Modifying components (p. 27) Conceptual components (p. 27) Converting a conceptual component to a detailed component (p. 28) Tips on working with components (p. 29)


23

Creating components You create different types of component in different ways. For example, you select existing parts to indicate which members a connection or a detail is attached to. You need to pick points to indicate the location or length of a detail or a modeling tool. See also Selection order (p. 13). When you create connections, Tekla Structures prompts you to select the main part (the part secondary parts connect to), then the secondary part(s). For an example of using a connection, see Example: Adding an end plate (p. 24). Status

Tekla Structures uses different-colored component symbols to show the status of connections and details:

Color

Status

Tip

Component created successfully. Green Component created, but has problems.

Often occurs when bolts or holes have an edge distance less than the default value for that component.

Component failed.

A common reason is that the up direction is not appropriate. See Up direction (p. 13).

Yellow

Red

When applying a component that you are unfamiliar with, accept the default properties and apply the component. Then look to see what needs to be modified. This is quicker than trying to set the values for the component before seeing what the component actually creates.

Example: Adding an end plate This example shows how to create an end plate connection. The End plate (144) connection connects two beams, or a beam to a column, using a bolted end plate. To create the end plate connection: 1. 2. 3. 4.

24


In the component catalog, enter 144 and click Search. Double-click the End plate (144) component. Tekla Structures displays the component dialog box and starts the End plate (144) command. Click Apply to create the component using the default properties. Tekla Structures prompts you to select the main part (column) and then the secondary part (beam). Tekla Structures creates the connection.

5.

Select the next main part or interrupt the command.

If you need to change the number of bolts or plate dimensions, for example, you need to modify the component. For more information, see Modifying components (p. 27). If you use incorrect properties, Tekla Structures may fail to create the component. For more information, see Creating components (p. 24).

Example: Adding a base plate and anchor rods Component catalog contains several base plate details. This example shows how to create a base plate and anchor rods. Before you start:

• •

create a column create an elevation view

To add a base plate to a column: 1. 2. 3.

Open an elevation view. Open the component catalog. Enter base plate in the Search field and click Search.

4.

To view pictures of the components in the search results, click the Thumbnails icon


.

25

5. 6. 7.

Click Base plate (1004). This component creates a base plate with anchor bolts. The prompt Pick part appears on the status bar. Select the column. The prompt Pick position appears on the status bar. Pick the point at the base of the column to indicate where to create the base plate. 8. Tekla Structures creates the base plate. 9. Examine the component to see if you need to make any changes. 10. Check that the connection symbol is green, which indicates that the connection was created successfully. 11. Change the dimensions of the anchor rods. To make it easier to select components, click the Select component icon

.

12. Double-click the component to open the Tekla Structures Base plate (1004) dialog box. 13. Go to the Anchor rods tab. Change the dimensions of the anchor rods. 14. To change only this base plate, select Ignore other types in the list in the top section of the dialog box:

15. 16. 17. 18.

Click Modify. Tekla Structures changes the dimensions of the anchor rods. Click OK to close the dialog box. Right-click and select Interrupt from the pop-up menu to end the command. Check that the connection symbol is green, which indicates that the connection was created successfully.

Example: Adding a beam to column connection Component catalog contains several beam to column connections. This example shows how to create a beam to column connection. Before you start:

• •

create a beam and a column create an elevation view

To create a beam to column connection: 1.

26


Open the component catalog.

2.

Select Beam to column connections in the list. The list of beam to column connections appears in the main pane. 3. Select Column with stiffeners (186). 4. The prompt Pick main part appears on the status bar. Select the column. 5. The prompt Pick secondary part appears on the status bar. Select the beam. 6. Tekla Structures creates the connection. 7. Click OK to close the dialog box. 8. Right-click and select Interrupt from the pop-up menu to end the command. 9. Check that the connection symbol is green, which indicates that the connection was created successfully. 10. Examine the component to see if you need to make any changes.

Viewing components You can create several views of a component to view it from different viewpoints. To create views of a component: 1. 2.

Click the component symbol to select the component. To create views, right-click and select Create View > Default Views of Component from the pop-up menu. Tekla Structures creates four views: front, end, top, and perspective.

To check dimensions, such as bolt locations and edge distances, work in the Component front view and use the Measure tool.

Modifying components To modify a component, double-click the component symbol in the model. The component dialog box appears. This is where you modify the component properties.

If you have Select component switched on , you do not have to pick component symbol, but you can just pick any object belonging to a component. This is the only method for selecting custom parts, because they do not have any symbol. You can also indicate which connections and details are affected by the modifications:

•

•

Modify connection type: If you have selected several connections details, clicking the Modify button modifies all the selected connections and details irrespective of their type. If

the connection type is not the same as in the dialog box, Tekla Structures changes the connection type. Ignore other types: Tekla Structures only modifies connections and details of the type shown in dialog box.

Conceptual components Conceptual components are meant to be used as reference information for further fabrication detailing. Conceptual components look similar to detailed components but do not include the option to change part numbering or assembly numbering settings.


27

Conceptual components can be created only with Engineering and Reinforced Concrete Detailing configurations. However, you can edit conceptual components in Full, Steel Detailing, or Precast Concrete Detailing configurations. Conceptual components can be converted to detailed components that include all the information needed for fabrication, such as assemblies, cast units, and reinforcing bars. The conversion to detailed components can be done in Full, Steel Detailing, or Precast Concrete Detailing configurations. Modifying part properties, such as the size of the component main part, does not automatically convert a detailed component to a conceptual one, or vice versa. For example, if you use the Engineering configuration and modify the model, detailed components do not convert back to conceptual components.

Tips on working with components No component created

If you have difficulty applying a component, check the status bar for prompts. For example, you may need to click the middle mouse button to stop selecting parts, before Tekla Structures creates the component.

Many parts found

If you are applying a connection that only allows for one secondary part, you may see the message Many parts found on the status bar. This means that Tekla Structures cannot determine which parts to connect. You may have several parts in the same location, or the view may be set too deep.

Switch parts on/ off

If the component does not create the parts you need by default (for example, stiffener plates), look for a switch to turn them on. If there is no switch, try entering a value in the thickness field for that part (for example, on the Stiffeners tab). If the component creates parts you do not need, look for the switch to turn them off. If there is no switch, enter a zero (0) in the thickness field for that part.

Default: Tekla Structures creates stiffeners or uses value retrieved from AutoDefaults. Automatic: Tekla Structures creates or omits stiffeners depending on the situation in the model.

Tekla Structures does not create stiffeners

Tekla Structures creates stiffeners.

Entering valid profiles

You need to specify profiles for some components. If a component fails, try entering a valid profile.

1.4 Defining parts and plates Use the Parts tab to define the parts that Tekla Structures creates when you use a component. Topics

Using the dialog box (p. 29) Dimensioning parts (p. 30) Defining materials (p. 32)

Using the dialog box Some components list all parts on one tab, others list parts on separate tabs as shown in the following examples. One Parts tab

Where there is one tab, the label is usually Parts or Plates.


29

Several Parts tabs

Parts can also appear on separate tabs. For example, in connection 56, Corner tube gusset, the parts appear on both the Gusset and Brace conn tabs.

Dimensioning parts Use the Parts tabs to dimension specific part types in components.

To delete a part, enter zero (0) in the t (thickness) field.

Plates Enter the following dimensions for plates:

Dimension

Description

t

Plate thickness

b

Plate width

h

Plate height

You do not have to enter these dimensions for every component type, as Tekla Structures determines the plate shape differently for different components. For example, in end plate connections, Tekla Structures calculates width and height using the number of bolts and bolt edge distances. Click Help in a component dialog box to check which dimensions you need to enter.

Beams To specify a library or parametric profile to use for beams:

30


•

Enter the profile name.

•

Or click

, and select a profile from the profile catalog.

The profile must exist in the profile catalog.

Part position number Use the Pos_no field to enter the part position number for each part the component creates. This overrides the settings on the Tools > Options > Options... > Components tab. Specify a prefix and a start number, as shown below.

Prefix Start number Some component dialog boxes have a second row of Pos_no fields for you to enter the assembly position number.

Using the Components tab To set the default prefix and start number for all the parts that components create, click Tools > Options > Options... > Components. You define different prefixes and start numbers according to the part’s relationship to other parts in the component. Separate the prefix and part number using the \ character (for example, p\1).


31

Prefix Part number

Defining materials To define the materials for the parts that components create, click against the Material field. Tekla Structures opens the Select Material dialog box. Click a material type, then click the material to use for the part.

32


Using the Components tab To set the default part material for the parts that components create, click Tools > Options > Options... > Components tab, and use the Part material field. Tekla Structures uses this default if you leave the Material field blank in the component dialog box when you apply the component.

1.5 Defining bolts and welds Use the Bolts or Welds tabs to define which bolts, assemblies, and welds to use in specific components. Topics

Using the Bolts tab (p. 33) Defining bolts (p. 35) Creating holes (p. 35) Number of bolts and spacing (p. 36) Bolt group orientation (p. 36) Bolt group pattern (p. 37) Edge distance (p. 37) Bolt position (p. 37) Defining slotted holes (p. 39) Deleting bolts (p. 40) Defining bolt assemblies (p. 41) Welds (p. 41)

Using the Bolts tab This illustration shows the properties you can set on the Bolts tab of component dialog boxes:


33

Slotted hole dimensions Slotted to create slotted hole in part Check bolt components to include (bolt, washer, screw). Shank length protruding from the nut Bolt spacing - vertical Number of bolts

34


Enter bolt order number of bolt to delete. Edge distance Bolt spacing (horizontal) Number of bolts Bolt group pattern Horizontal Vertical

Defining bolts Use the following fields on the Bolts tab to specify the type of bolts to use in individual components:

Indicate if the thread can be inside bolted parts when using bolts with a shaft. Has no effect if using full-threaded bolts.

Site/Workshop

Location where bolts should be attached.

Increasing bolt length To allow for additional material thickness, increase the length of the bolt on the Bolts tab. For example, you could use this for painted parts. Enter extra bolt length

Tekla Structures uses this value in bolt length calculation. See Bolt length calculation.

Creating holes To only create a hole, deselect all the components in the illustration on the Bolts tab.


35

Number of bolts and spacing Use the Bolts tab to specify the number of bolts and bolt spacing, both horizontally and vertically. Enter the number of bolts in the shorter field, and the spacing between bolts in the longer field, as shown below. Use a space to separate bolt spacing values. Enter a value for each space between bolts. Example

For example, if there are 3 bolts, enter 2 values.

Number of bolts Bolt spacing The settings above result in this bolt group layout:

Bolt group orientation Some connections include the following options on the Bolts tab to orientate bolt groups:

Option

Description Square. Staggered in the direction of the secondary part.

Sloped in the direction of the secondary part.

36


Bolt group pattern For some components you can select different bolt group patterns. You have the following options:

Option

Edge distance Edge distance is the distance from the center of a bolt to the edge of the part. Enter top, bottom, left, and right edge distances on the Bolts tab. A dimension line on the illustration shows each dimension. See also Using the joints.def file (p. 46).

Edge distance dimension line Enter edge distances here

Bolt position In the list box on the Bolts tab, select an option to indicate how to measure dimensions for vertical and horizontal bolt position. Then enter the dimension in the fields indicated below. If you leave this field blank, Tekla Structures uses a system default value.

Defining slotted holes To define slotted holes in components: 1. 2. 3. 4.

Open the component properties dialog box and click on the Bolts tab. Different bolt groups may appear on different tabs in different dialog boxes. Set Hole type to Slotted. Select which parts have slotted holes from the Slots in list box. Select No to create round holes. To shape slotted holes, enter the x or y dimensions of the hole. To produce a round hole, enter zero (0) for both dimensions.


39

Slotted hole length = x or y dimension + Bolt size + Tolerance

For some components you can specify which parts have slotted holes using the Bolts tab. For example, Clip angle (141), Shear plate simple (146).

You can also use the Bolt command to modify bolt groups after creating components. For more information, see Holes.

Deleting bolts To delete bolts from a bolt group: 1. 2. 3. 4. 5. 6. Example

Double click the component symbol to open the component dialog box. Go to the Bolts tab. Check Delete. Enter the bolt number(s) of the bolt(s) to delete, separated by a space. Bolt numbers run left to right and top down. Click Modify to change the selected component. Click OK to exit the component dialog box.

You start with this bolt group:

You enter the following bolt numbers:

The bolt group now looks like this:

1.6 AutoConnection Introduction

Use AutoConnection to automatically select and apply connections with predefined properties to selected parts. Use AutoConnection to have Tekla Structures automatically create similar connections for similar framing conditions.

Topics

Using AutoConnection (p. 42)

Using AutoConnection Use AutoConnection to have Tekla Structures automatically create connections using a predefined set of rules, or rule group. Creating connections

42

To create connections using AutoConnection: 1. 2. 3.


Pick the parts to connect. Click Detailing > AutoConnection... to display the AutoConnection dialog box. Select a rule group in the first list box on the Rule groups tab as shown below.

Rule group for AutoConnection Rule group for AutoDefaults 4.

Click the Create connections button.

When you use AutoConnection, Tekla Structures ignores the properties in the connection dialog boxes and creates connections using the properties defined in the rule group. Tekla Structures does not modify existing connections. You can change the properties of connections you create using AutoConnection. Additional options

Use the options on the Advanced tab to indicate which rule groups you want to use for each Framing condition (beam to beam web, beam to beam flange, etc.). You also have the option not to apply a rule group, or to apply a specific connection.


43

Example

You can use a rule group for all framing types other than beam to column flange, and indicate a particular connection to use for that framing type.

Options

Use Connection selection to indicate your preferences for each framing condition. You have the following options:

AutoDefaults

Tekla Structures applies the properties of the rule group you have indicated in the first list box on Rule groups tab.

No AutoDefaults

Tekla Structures applies the default connection properties. See Automatic and default properties (p. 14).

1.7 AutoDefaults Introduction

Use AutoDefaults to automatically apply connections. When you use AutoDefaults, Tekla Structures automatically creates connections with predefined properties. For example, you can use AutoDefaults to automatically adjust the thickness of each base plate you create, according to the main part profile. If the main part profile changes, Tekla Structures will also automatically adjust the thickness of the base plate.

Topics

Using AutoConnection (p. 42) Using AutoDefaults (p. 45) How to use AutoDefaults effectively (p. 46) Checking AutoDefaults properties (p. 46) Checking AutoDefaults rules (p. 46)

Using AutoDefaults With AutoDefaults you can have Tekla Structures apply connection properties using a predefined set of rules. You can use AutoDefaults together with AutoConnection to define connection properties, or separately to define the properties of a single connection. To use AutoDefaults for a single connection: 1. 2. 3.

Open the connection dialog box. On the General tab, select a rule group (the rule group cannot be None). On all the tabs, set the fields that you want AutoDefaults to override to Default by

4.

selecting the options marked with the arrow symbol. Click Apply to create the connection using AutoDefaults.

To quickly set all the fields in a dialog box to Default, load in the connection dialog box.


45

How to use AutoDefaults effectively Use default values when you create a connection, then use AutoDefaults to modify the properties. If you manually modify connection properties after using AutoDefaults, Tekla Structures will not automatically update the connection properties, even if AutoDefaults is active. AutoDefaults does not change connection properties that have been modified. It only modifies connection properties in fields containing the default properties. For example, you have manually set a base plate thickness of 20 mm in the Base plate dialog box of a connection. AutoDefaults is active and sets plate thickness according to the main part profile. If you modify the main part profile, Tekla Structures does not update the base plate thickness. It remains at 20 mm.

Checking AutoDefaults properties To check the properties AutoDefaults has applied to a connection: 1. 2. 3.

Double-click the connection symbol to open the connection dialog box. In the list box in the upper left corner of the dialog box, select . Click Load. Tekla Structures shows the applied properties in the fields. You can also see all the combined properties used for that connection.

Checking AutoDefaults rules You can check which rules AutoDefaults has used for a particular connection. 1. 2.

Select the connection symbol and right-click. Select Inquire.

Tekla Structures shows the rule group and rule sets that the connection passed. You can also see all the properties files used for that connection.

1.8 Using the joints.def file This section explains how to use the joints.def text file to set the default properties for different connection types. Not all connections use joints.def.

If you are new to using joints.def, we suggest you read each of the topics in this section thoroughly before making any changes.

Topics

About joints.def (p. 47) Defining general defaults (p. 48) Defining bolt diameter and number of rows (p. 50) Defining other bolt and part properties (p. 51) How Tekla Structures uses joints.def (p. 57) Connections that use joints.def (p. 48)

46


About joints.def Changing the joints.def file changes the default values for different connection types. You can open the joints.def file in any standard text editor.

Tekla Structures only uses the values in joints.def for blank fields. AutoDefaults and manual entries override joints.def.

If you use joints.def, you can still use some system default properties. To force Tekla Structures to use the system default for a particular property, give it the value -2147483648 in joints.def. By default, Tekla Structures includes the joints.def file in the system folder. Tekla Structures searches for joints.def in the standard search order.

How joints.def works For each connection type, Tekla Structures follows these steps to assign bolt and part properties. 1.

Tekla Structures determines bolt diameter and number of bolts according to the following criteria:

Connection type

According to

Clip angle

Secondary beam height

Shear plate


End plate


Gusset

Length of angle profile

Diagonal

Profile height

2.

Tekla Structures uses bolt diameter to assign other bolt and part properties.

How to read joints.def Lines beginning with // are comment lines. They are there to help you read the file, Tekla Structures does not use the information in comment lines. The first few lines contain some general settings: Set the following line to the unit of measure appropriate to the version you are using (for example, inches in the Imperial version).

To have Tekla Structures use the default values in joints.def, set the following line to 1. Set it to 0 to have Tekla Structures use the system defaults.

Properties for each connection type appear in individual sections, as shown below. Each section begins with a header row containing the column labels. Do not add columns to the file.


47

Entering values When you edit joints.def:

• • • •

Enter absolute values or names Do not use feet and inch symbols Ensure that profiles exist in the profile catalog Ensure bolts exist in the bolt catalog.

Connections that use joints.def Only the following connections use joints.def

Defining general defaults If Tekla Structures cannot find a property for a connection in the connection-specific sections of joints.def, it looks for the default property in the General section. Example

In clip angles, Tekla Structures uses the default bolt diameter in the General section if the secondary beam height is larger than the highest value in the Clip angle section of joints.def. The properties in the General section of joints.def are:

To find the bolt dimensions to be used with an L6X6X1/2 profile in a clip angle connection: 1. 2.

Tekla Structures searches the rows beginning PROFILEBOLTDIM for L6X6X1/2 in the PROFILE TYPE-DEPENDENT BOLT DIMENSIONS section of joints.def. If there is no match, Tekla Structures searches the rows beginning ANGLECLBOLTPART in the CLIP ANGLE section of joints.def.

How Tekla Structures uses joints.def This example explains how Tekla Structures calculates bolt diameter and other properties using joints.def. We are using a Bolted gusset (11) connection. The height of the diagonal profile is 10".

• •

•

Tekla Structures calculates bolt size and number of bolts according to profile height. It searches the BOLTHEIGHT rows for a profile height of 10". The profile height is greater than 8.0 but less than 12.0, so Tekla Structures uses the row with the profile height 8.0. This sets the bolt diameter to 0.75.

Tekla Structures assigns the bolt and part properties according to the bolt diameter. It searches the DIAGBOLTPART rows for a bolt diameter of 0.75.

1.9 Using Excel in connection design You can link system components and Excel spreadsheets, so when a component is applied or modified, an associated Excel spreadsheet application can be run. The configuration information is passed from the component to the spreadsheet, calculation run within the spreadsheet and component properties passed back to the connection.

You can use Excel in connection design for all steel components that have the Design tab in their properties dialog box.

Tekla Structures includes sample spreadsheet for connection design and a template spreadsheet you should use to create your own spreadsheet applications to use with Tekla Structures components. Before you start:

• •

Create the connections and parts. Create the Excel spreadsheet for connection type, or use a predefined file. See more in Setting up Excel files (p. 59).

To use the Excel spreadsheet for connection design: 1. 2. 3. 4. 5. 6. Topics

Double-click the connection to open the connection properties dialog box. Go to the Design (or Design type) tab and select Excel in the External design list box. Click Modify. The connection properties are transferred from Tekla Structures to a connection type specific Excel spreadsheet, where the properties are calculated. The calculated properties are saved to an output file. The modified properties are transferred back to Tekla Structures and the connection is modified according to the changes.

Setting up Excel files (p. 59) Sample implementation (p. 59) Indicating component status (p. 62)

58


Setting up Excel files The following list describes what kind of files are needed for performing connection design with Excel:

• •

Visual Basic script file linking Tekla Structures with external software. Excel spreadsheet containing calculations.

• • •

When you run the connection design, the connection properties and information of the main and secondary parts are transferred to the Input and Component sheets of the spreadsheet.

Connection specific result file, which displays the modified connection properties is stored to model folder.

• • • File names and locations

Component type specific spreadsheet, which contains predefined calculations.

This file is created automatically from the Calculation sheet of the spreadsheet. The file is updated each time you modify the connection. Calculation results can be stored as Excel spreadsheet, HTML or PDF format, depending on how calculation spreadsheet is configured.

Excel.vb file (located in the ..\Tekla Structures\\environments\common\exceldesign folder) defines the Excel spreadsheet file names and the locations. Excel searches for the spreadsheet in the following order and with following name: 1.

File named component_ + number or name + .xls, from the current model folder: ..\\exceldesign For example, ..\test_model\exceldesign\component_144.xls

2.

File name and path defined with advanced option XS_EXTERNAL_EXCEL_DESIGN_PATH: XS_EXTERNAL_EXCEL_DESIGN_PATH (=%XS_DIR%\environments\common\exceldesign\) + "component_" + number + ".xls"

By default, the result file is stored in the model folder and named with component ID. For example, component_9502_res.xls.

Sample implementation Below is descibed the contents of an Excel spreadsheet which is used for End plate (144) connection: When user clicks Modify in the End plate (144) properties dialog box, Excel.vb file calls Excel spreadsheet named component_144.xls. Contents

The sample spreadsheet includes the following sheets: Inputs (user inputs on connection dialog).

•

Tekla Structures transfers the component properties from the component properties dialog box to this sheet.

•

60


Tekla Structures transfers the component geometry and information on the main and secondary parts (for example, part profiles) into this sheet. The component attributes in the spreadsheet are the same as in the corresponding .inp file. See more about .inp files in Input files. This sheet includes calculations (the calculations can be as Visual Basic macros in the sheet).

Calculation

•

Summary of calculation is collected to the Calculation sheet. This page or full Excel spreadsheet can be stored as a report of the calculation.


61

Outputs

•

Excel adds the modified values to the Output sheet. These values are tranferred back to the connection and connection in the model is modified accordingly.

Indicating component status When you use Excel in connection design, you can have Tekla Structures use different colored component symbols to indicate the status of a component in the model. To do this, include the error attribute on the Output page of the Excel spreadsheet for the component. The possible values are:

62


Value

Color

Status

1

Green

Bolt edge distances are sufficient. Passes the connection design check using the UK and US design codes embedded in the system.

2

Yellow

Bolt edge distances are insufficient according to the value in Tools > Options > Options... > Components.

3

Red

Tekla Structures cannot calculate the component properties. Possible reasons include:

• • • •

Incorrect connection direction Incorrect workplane Inappropriate connection selected The connection design check was carried out using the embedded UK and US design codes and the connection cannot support the loading defined by the user.

Introduction

Custom Components

Tekla Structures contains a set of tools for defining intelligent connections, parts, seams, and details, called custom components. You can create your own components, similar to Tekla Structures system components. Tekla Structures creates a dialog box for the custom component, which you can easily customize, if required. You can then use custom components in the same way as any Tekla Structures system component.

You can also edit custom components to create parametric custom components that automatically adjust to changes in the model. Audience

This chapter is aimed at people who know how to use Tekla Structures components.

Contents

This chapter includes the following topics, which are the steps you follow to create custom components:

• •

2.1 Defining custom components Introduction

You can build custom components either by exploding and modifying an existing component, or by creating the component objects individually. You then define a custom component by selecting the objects to include in the custom component, and specifying the information the user needs to input, for example, main part, secondary parts, or points they need to pick. You can now apply the custom component in a similar location in the model to where it was originally created.

To create a parametric custom component, you need to do some more editing. For more information, see Editing custom components (p. 73).

Go to Detailing > Component > Define Custom Component to define the properties of a new custom component. To browse a list of custom components, 1. 2. Topics

Press Ctrl + F to open the Component catalog. Select Search results > Custom.

Exploding components (p. 66) Defining a custom component (p. 66) Custom component types (p. 70) Custom component basic properties (p. 72)

Exploding components Explode Component is a very useful command to use when defining custom components. It

ungroups the objects in an existing component, you can then remove and modify parts and other objects in the component. To explode a component: 1. 2. 3.

Click Detailing > Component > Explode component. Select the component to explode. Tekla Structures ungroups the objects in the component.

Defining a custom component You can define and save custom components in the component library. Before you can define a custom component, you need to create a sample component in the model containing all the necessary component objects, such as parts, fittings, bolts, and so on.

66


To quickly create a custom component, explode a similar existing component, then change it to suit your needs. See Exploding components (p. 66).

Use the Custom Component Wizard on the Detailing menu to define the properties of a new custom component. See the following example.

Follow the steps in the custom component wizard. Some steps are different for different types of custom component.

Example

In the following example we will create a custom component based on an existing end plate component that we have exploded.

To explode a component, select the component, right-click and select Explode Component from the pop-up menu.

1.

Click Detailing > Component > Define Custom Component... to open the Custom Component Wizard dialog box.

2. 3.

On the Type/Notes tab, set Type to Connection. Enter a Name for the custom component. On the Position and Advanced tabs, set the Position type and other properties for the custom component. For more information on other properties, see Detailing > Component > Define Custom Component... (p. 117). Click Next. Select the objects to use in the custom component and click Next.

4. 5.


67

You can use area select to select the objects to include. Tekla Structures ignores the main part, secondary parts, grids and component symbols when you are selecting objects to include in the custom component. 6.

68


Select the main part and click Next.

7.

Select the secondary part(s). To select several secondary part(s), hold down the Shift key while you select the parts. The maximum number of secondary parts in a custom component is 30. Pay attention to the order in which you select secondary parts. The custom component will use the same selection order when you use it in a model.

8.

Click Finish.


69

9.

Tekla Structures displays a component symbol for the new component.

You have now defined a simple custom component, which you can use in similar locations to where it was originally created. This component is not parametric and Tekla Structures does not adjust dimensions to suit any changes in the model. To create a parametric custom component, see Editing custom components (p. 73).

Defining a custom component (p. 66) Using a custom component (p. 111) Detailing > Component > Define Custom Component... (p. 117)

Custom components in a new Tekla Structures version When you move to a new version of Tekla Structures, always check that custom components created in older versions work correctly in the new version. When you open custom components made with an older version of Tekla Structures in the Custom component editor, and the new version contains improvements requiring update, Tekla Structures asks whether you want to update the component. If you do not update the component, it works in the same manner as in the version where it was originally made, but you do not gain the benefits of the improvements. If you choose to update the component, you need to check and sometimes even recreate dimensions depending on the improvements. When you delete a dimension and create a new one (even with the same name), also the equations containing the dimension need to be edited, because the dependency created by the equation is lost when a dimension is deleted. You can recreate the dimensions and edit the equations easily in the Custom component editor.

2.2 Editing custom components Introduction

To make a simple custom component parametric, so that it adapts to changes in the model, you must edit it in the Custom component editor. Here you can build dependencies between component objects and model objects. For example, you could specify that the size of a stiffener depends on the size of the beam. So, if you change the size of the beam, the size of the stiffener also changes. You can also add distance variables, for example to specify the gap between a plate and a beam.

Custom component editor Use the custom component editor to modify custom components and create intelligent, parametric custom components. First, create a custom component in the model. Opening the editor

To open the custom component editor: 1. 2.

Click Detailing > Component > Edit Custom Component. Select the custom component. The Custom component editor opens. It shows the Custom component editor toolbar, the Custom component browser and four views of the custom component.

Custom parts do not have a component symbol. To be able to select custom parts, make sure the Select components switch is active.

Custom component toolbar

The toolbar contains the following icons and list boxes:

Icon/ List box

Description Creates a distance. Creates a reference distance. Creates distances automatically. Creates a construction plane. Creates a construction line.

Plane types

Displays plane types you can use when defining distance variables. For more information, see Plane types (p. 125).

Define part dimensions, spacings, gaps, etc. that will be visible in the custom component dialog box.

Creating distance variables (p. 79)

Bind component objects to model objects so that component objects adjust for new beam size or profile.

Automatic distances (p. 130)

Create formulas to calculate values, for example for calculating bolt edge distance using bolt size.

Creating parameters that use formulae (p. 86)

Use the custom component editor to modify custom component. You can open a custom component in the editor even if you have already used it in a model. When you have edited the custom component, you can choose to apply the changes to all copies of the custom component, or to save the component with a new name.

• •

Closing the editor


To apply your changes to the library and to all copies of the custom component in the model, use the Copy component to library command. To save the edited custom component with a new name, use the Copy component to library with new name command and enter a new name for the custom component.Tekla Structures does not apply the changes to the other copies of the custom component in the model.

To close the custom component editor: 1. 2.

. Click the Close icon Tekla Structures asks if you want to save the custom component with its original name.

If you click Yes, Tekla Structures will overwrite the copies of the custom component in the library and the model.


75

Creating automatic backup files

When you modify a custom component, Tekla Structures automatically creates a backup file of the custom component. The backup files have the extension .inp_bak, and they are located in the model folder. Tekla Structures displays a notification when the backup file is created. See also Custom component browser (p. 76)

Custom component browser The Custom component browser shows the contents of a custom component in a hierarchical, tree-like structure. The Custom component browser works with Custom component editor views. Click a part in the view and Tekla Structures highlights it in the browser, or click a part in the browser to have Tekla Structures highlight it in the view. The Custom component browser contains the following information about a custom component:

Model objects, to which custom component is attached The objects the custom component creates You can create links between custom component variables and component object properties You can create links between custom component parameter variables and component object properties. For example, variable "m" defines the material grade for all plates in your component. It appears as "Material = m" in the Custom component browser (see above illustration). "m" is also a field in the custom component dialog box. When a user enters a value in the "m" field in the dialog box for plates, Tekla Structures saves the value to the part properties in the model.

76


Popup menu

You can also use the popup menu in the Custom component browser to copy names, values, and references from main and secondary parts in the component. Then use them in the Variables dialog box to define the properties of custom components. For example, to report how many secondary parts to pick when applying a component, you can use a variable called Number of secondaries. You can then use the variable in formulas, and copy the name, value and reference to other custom components.

Copies just the value the object currently has Copies the link to the property. Link is dynamic, so when the property later changes the reference reflects the change Using custom part properties

If you have created a custom part in to your model, you can access the object properties of the custom part when the custom part is used an input part. You can access the name, profile, material and class of the input custom part, and use the properties of the input part in the component objects. This is useful in cases where the material for a new part needs to be taken from the inner or outer layer of an existing part.

• •

The Component parameters category lists all distances and parameters that belong to the current custom component. The Model parameters category lists all distances and parameters in the current model.

When you select a distance variable from a list, Tekla Structures highlights it in the model.

To delete the selected distance or parameter, click Delete. To add a new parameter variable, click Add. For more information, see Display variables (p. 120). Topics

Creating distance variables (p. 79) Creating reference distances (p. 81) Using magnetic construction planes (p. 84) Creating parameter variables (p. 85) Creating parameters that use formulae (p. 86)

Creating distance variables Use distance variables to bind handles, fittings, cuts, and so on, to planes so that the custom component can adapt to different situations, such as different main profile shapes and sizes. You can create a distance variable from point to plane or from plane to plane. These distances can be visible or hidden. Use visible distances when you want the user to enter a distance value in the custom component dialog box. To simply bind objects to planes, use hidden distances. You can bind the corners of polygon plates also in directions other than the plane of the plate. You can, for example, bind the corner of a contour plate in the z direction.

Use the automatic distances command to automatically create distances for the handles of picked components:

For more information, see Automatic distances (p. 130). How

In this example we will create a distance variable that binds the upper edge of the end plate to the upper flange of the secondary part. Whenever you create this custom component in the model, the end plate will follow the upper flange, regardless of the profile or size the secondary part. Before you start, ensure that the part representation is set to rendered. Part surfaces and available planes can be selected only in rendered views. To create the distance variable: 1.

Select the object from which to measure the distance. This object will follow the plane to which you bind it. In this example, select the plate’s topmost reference point (magenta or yellow)

2.

Click the Create distance icon or right-click the reference point and select Bind to Plane from the pop-up menu. Move the mouse cursor over a view to see the available planes.

Create distance (p. 128)

Creating reference distances Use reference distances to measure the distance between two points or a point and a plane. You can then use the reference distance in calculations, for example, to determine the spacing of rungs on a ladder. A reference distance changes as you move the objects it refers to. Tekla Structures displays reference distances in orange. You cannot move objects by changing their reference distances.

To be able to select reference distances, make sure the Select distances switch is active.


81

Example

In this example we will define several variables: distances, reference distances, and parameters, and use them in a custom component that creates a ladder with rungs spaced at set intervals, for any length of ladder. Here is how the variables appear in the Variables dialog box:

1. 2. 3. 4.

Create a ladder frame with one rung 285 mm from the bottom of the frame. To make the ladder a custom component, select Detailing > Define custom component... and follow the steps in the Custom component wizard. Right-click the ladder and select Edit custom component... from the popup menu. In the Custom component editor, use the Array of objects (29) component to create the rest of the rungs. Use the Create distance tool to bind the bottom rung to the bottom of the ladder frame (D1 and D2 in the in the Variables dialog box). See Create distance (p. 128) for step-by-step instructions.

82


5.

Use the Create reference distance tool to create a reference distance from a handle on the bottom rung to the plane at the top of the ladder. • Select a rung handle

•

On the Custom component editor toolbar, click the Create reference distance icon

•

Bind the handle to the horizontal plane at the top of the ladder frame.

This distance appears as D3 in the Variables dialog box. 6. 7. 8.

Go to the Variables dialog box. Add a parameter (P1) to define rung spacing. Give it the value 250. Add another parameter (P2) to define the distance from the bottom of the ladder to the first rung. Give it the value 285. 9. Give the distances D1 and D2 the formula =P2. This forces both distances to be the value defined by P2. 285 in this case. 10. Add a new parameter (P3) to define the number of rungs. Give it the formula =(D3-P2)/P1. 11. We want the number of rungs to be an integer, so add a new parameter (P4) and give it the formula =ceil (15.52).This rounds P3 up to the nearest integer. 12. Add a new parameter (P5) to calculate the distance between the rungs. Give it the formula =(D3-P2)/P4. This formula subtracts the distance from the bottom of the ladder to the bottom rung from the reference distance (D3) and divides the result by the number of rungs (P4). 13. Go to the Custom component browser and link the following properties of the Array of objects (29) component to parameters P4 and P5, as shown below:


83

When you use this custom component to create a ladder in a model, Tekla Structures automatically calculates the correct spacing for the rungs. See also

Create reference distance (p. 129) Defining custom components (p. 66)

Using magnetic construction planes You can bind several objects at one time using magnetic construction planes. The objects directly on a magnetic plane will move with the plane. So you only need to create a distance variable for the plane and not for each object separately. As you can see from the example below, it is much easier and faster to use magnetic user planes than to bind handles with individual distance variables. Example

84

Different methods of binding chamfers to the inner face of a flange:


Option 1: Control the stiffeners by using 4 magnetic construction planes - one in each direction. Then you only bind each magnetic plane with one distance variable Option 2: Bind each chamfer separately - a total of 32 bindings For more information on magnetic construction planes, see Construction plane (p. 126).

By default, the handles of contour plates are not visible. To show them, set the advanced option XS_DRAW_CHAMFERS_HANDLES to HANDLES.

Creating parameter variables You can use parameter variables to set basic properties for objects that custom component creates, for example, name, material, profile, position number, etc. Example

In this example we create a parameter variable "Weldsize" that sets all welds in a custom component to a given size: 1. 2. 3.

On the Custom component editor toolbar, click Click the Add button. Enter following information: • Name = Weldsize

• • • • • •

to open the Variables dialog box.

Formula = Value = 0.0 Variable type = parameter Value type = length Visibility = Show (this makes Weldsize visible in the dialog box) Label in dialog box = WeldSize

4. 5.

Click OK button to close the dialog box. In the Custom component browser, click Component objects > Weld > General properties and right-click Size above line and select Add equation. Type after the equal sign "Weldsize". Repeat this step for all welds.

6. 7.

Click Save. Click Close icon to exit the Custom component editor.

Your custom component dialog box should now contain the field WeldSize. When anyone creates the component, all welds are of the size you enter in the WeldSize field.


85

Creating parameters that use formulae This example shows how to create a hidden parameter variable that includes a formula to set weld size to half the thickness of the secondary part flange. This variable will not be visible in the custom component dialog box. When you create the component, Tekla Structures uses the thickness of the secondary part flange to calculate the size of the weld(s).

86

1.

In the Custom component browser, click Input objects > Secondary parts > Part > Profile properties and right-click Flange thickness 1 and then select Copy reference. Tekla Structures copies the reference to secondary part flange thickness to the Windows Clipboard.

2.

In the Custom component editor toolbar, click

3. 4. 5.

Click Add button. Set Variable name to w. Click the Formula field, type =, then right-click and select Paste. Tekla Structures pastes the reference to flange thickness from the Clipboard. Now enter *0.5. Formula should now read: =fP(Flange thickness 1.1525)*0.5.


to open the Variables dialog box.

In the Custom component browser, click Component Objects > Weld > General properties and right-click Size above line and select Add equation. Type in after the equal sign "w". Click OK button to close the dialog box.

2.4 Functions to use in formulas This section lists all the functions you can use in formulas in custom components. Formulas always begin with the equals character (=). You can use the following functions in formulas:

• • • • • • •

Reference function (p. 88) Mathematical functions (p. 89) Statistical functions (p. 90) Data type conversions (p. 91) String operations (p. 91) Trigonometric functions (p. 93) Framing condition functions (p. 93)

Arithmetic operators You can use the following arithmetic operators:

Operator

Description

Notes

+

addition

Use also to create strings of parameters.

-

subtraction

*

multiplication

Multiplication is faster than division, so it is faster to use =D1*0.5 rather than =D1/2.

/

division

Logical statement You can use if-then-else statements to test a condition and set the value according to the result: =if (D1>200) then 20 else 10 endif

You can also use the operators && (the logical AND operator) and || (the logical OR operator) inside the if statement.

•

&& - both conditions must be true


87

•

|| only one condition must be true

For example to use a value 6:

•

=if (D1==200 && D2<40) then 6 else 0 endif

D1 must be 200 and D2 must be less than 40.

•

=if (D1==200 || D2<40) then 6 else 0 endif

D1 must equal 200, or D2 must be less than 40.

Reference function A reference function refers to the property of another object, such as the plate thickness of a secondary part. Tekla Structures refers to the object on the system level, so if the object property changes, so does the reference function value. fP(propertyname, ObjectId) To ensure the function includes the correct parameters, cut and paste it from the Custom component browser:

1. 2.

Right-click the property in the Custom component browser and select Copy reference. Right-click the Formula cell in the Variables dialog box and select Paste.

Note that slope and skew are relative to a beam framing into a column.


93

Side view Top view Slope Skew Column Beam Beam to beam

If you are working with two beams, "slope" is actually the skew of the beam framing into the other beam, and the vertical slope of the beam relative to the main is actually the "skew" angle.

Side view Top view Skew Slope Beam

94


Limitations

• •

These functions do not return positive and negative "slope" and "skew" values. So it is not possible to determine up or down "slope" and left or right "skew" with these functions. Maximum skew angle to return is 45 degrees.

2.5 Defining custom component properties This section explains how to add different properties for custom components. Topics

Adding an option to create parts (p. 95) Defining bolt size and standard (p. 96) Defining bolt group location (p. 97) Replacing a sub-component (p. 99) Changing the properties file (p. 101) Defining meshes in custom components (p. 102)

Adding an option to create parts To include an option to create or not create parts in a custom component properties dialog box: 1. 2. 3. 4.

In the Variables dialog box, add a new property Set the Value type to Yes/No, Set Visibility to Show Enter a Label to display in the custom component dialog box:

5.

In the custom component browser, link the property to a part:


95

6.

Save the custom component and exit the custom component editor. When you open the custom component properties dialog box, you now have the option to create or not create the part:

Defining bolt size and standard To add an option for selecting the bolt size in the custom component, you must add two options:

• •

Bolt size Bolt standard

They work together and cannot be used separately.

To define the bolt size and standard options:

5.

on the Custom Component editor toolbar to open the Click the Variables icon Variables dialog box. Click Add twice. Now you have two variables P1 and P2. In the Value Type field, select Bolt size for P1 and Bolt standard for P2. Tekla Structures automatically adds the extensions "_diameter" and "_screwdin" to the name of the variables. Do not change these extensions. Change P2_screwdin to P1_screwdin. The prefix must be the same, otherwise the variables do not work. Modify P1_diameter label to "Bolt size" and P1_screwdin label to"Bolt standard".

6.

In the custom component browser, link the parameters to the bolt:

1. 2. 3.

4.

96


7.

Save the custom component and exit the custom component editor.

Defining bolt group location To define the vertical distance from the secondary beam top flange to the first bolt, we add the following option to the custom component dialog box.

This option requires a distance that binds the bolt group handle to the secondary beam top flange and a parameter for inputting the value in the user interface. 1.

Double-click bolts in the custom component editor view. The Bolt properties dialog box appears. Remove any dimensions from the Offset fields, then click Modify. Bolts will move to the same level with the first handle of the bolt group.


97

2.

Select the bolts, then select the top handle. Right-click and select Bind to plane from the popup menu.

3.

Select the top flange of the secondary beam.

4.

A new distance parameter D1 appears in the Variables dialog box.

7.

Save the custom component and exit the custom component editor.

Replacing a sub-component Use the Name property in the Custom component browser to replace a sub-component inside a custom component with another sub-component. In this example we have created a custom component that contains a pair of cast-in embeds as sub-components (castin1 and castin2):

98


Castin 1 Then we will replace castin1 with castin2. To do this: 1. 2. 3.

Select the custom component. Right-click and select Edit custom component from the pop-up menu to open the custom component editor. In the Variables dialog box, add a new parameter. • In the Formula field, enter the name of the sub-component, castin1.

• •

4.

Set Value type to Component name. Enter a name for the parameter in the Label in dialog box field and set Visibility to Show.

In the Custom component browser, add the equation P1_name for both subcomponents:


99

The field Cast-in plate will appear in the dialog box of our custom component.

To change the sub-component: 1. 2. 3.

100


Click the ... button next to the name field. The Select component dialog box opens. Select the component to use (in our case castin2) and click OK. In the custom component dialog box, click Modify. Tekla Structures changes the component in the model.

Castin 2

Changing the properties file Use the Attribute file property in the Custom component browser to use different properties files for sub-components in a custom component. To add the properties file field to the custom component dialog box: 1. 2. 3.

Select the custom component. Right-click and select Edit custom component from the pop-up menu to open the custom component editor. In the Variables dialog box, add a new parameter. • In the Formula field, enter the name of the properties file (in our example, prop1).

• •

4.

Set Value type to Component attribute file. Tekla Structures automatically adds the extension _attrfile to the parameter name. Do not change this extension, but make sure that the prefix is the same as for the component name (in our example, P1). Enter a name for the parameter (in our example, Properties file) in the Label in dialog box field and set Visibility to Show.

In the Custom component browser, add the equation P1_attrfile for Attribute file.


101

To use another properties file for a sub-component, in the component’s dialog box, click the ... button next to the Properties file field, and then select the properties file from a list:

Defining meshes in custom components You can include rectangular meshes and change the mesh in your custom components.

To define a rectangular mesh type in a custom component: 1. 2. 3.

2.6 Managing and using custom components This section describes the custom component dialog box and explains how to use and manage custom components. Topics

Custom component dialog box (p. 105) Customizing the dialog box (p. 107) Using a custom component (p. 111) Managing custom components (p. 111) Performing actions on custom components (p. 113) Using Excel with custom components (p. 114) Using ASCII files with custom component (p. 114)

Custom component dialog box Tekla Structures automatically creates a dialog box when you define a custom component. By default the dialog box has a General tab for connections, details, and seams and a Position tab for parts. Tekla Structures automatically creates tabs containing the parameters and distances you set to visible in the custom component editor. Tabs are named Parameter 1, Parameter 2, etc. Each tab can contain up to 25 fields. If you have more than 25 visible fields, Tekla Structures creates another tab. A typical custom component dialog box looks like this:


105

This information relates only to details For seams you can select whether to place a seam at the point you pick, or let Tekla Structures automatically place the seam.

106


To place the seam at the point you pick, select the Place to picked positions checkbox To automatically place the seam, clear the Place to picked positions checkbox, and select one of the positioning options Tekla Structures creates an input file with the extension .inp for each dialog box in the model folder. You can modify the input file. See Customizing the dialog box (p. 107).

If you modify the input file, then edit and save the custom component dialog box using the custom component editor, you will lose the changes you made to the input file.

Customizing the dialog box To customize the dialog box that Tekla Structures creates for the custom component you need to modify the input file which defines the dialog box. The input file has the same name as the custom component and file extension inp. It is located in the model folder.

This topic is for advanced users. Take care when modifying an input file. Errors may cause the dialog box to disappear.

The input file is a text file that you can edit using any text editor, for example Notepad. You can customize the dialog box by:

• • • • • •

Changing the order of fields (p. 108) Changing the location of fields (p. 108) Renaming tabs (p. 109) Adding more tabs (p. 109) Adding pictures (p. 110) Preventing modifications (p. 110)

To use the modified custom component dialog box, save the input file, then close and restart Tekla Structures.

Changing the order of fields To change the order of fields, in the input file, change the last number in the parameter definition, as shown below:


107

Change these numbers to change the order of fields (listed from to bottom of dialog box)

Changing the location of fields To change the location of fields, in the input file, change the last number in the parameter definition. Enter three numbers to define the exact location of the field in the dialog box: the x coordinate, y coordinate, and length of field. The example below shows these values for the second field in the dialog box:

x = 374 y = 25 length = 160

Renaming tabs To rename a tab, change the tab definition in the input file. You can rename any tab except the General tab. In the example below, you would change the text Parameters 1 to the new tab name (for example, Parts):

108


Adding more tabs Each tab can contain 25 fields. If there are more than 25 visible fields, Tekla Structures creates another tab. You can also add tabs by modifying the input file. To add a second tab, edit the input file as shown below. Remember to adjust the location of the fields, if necessary.

Remember to adjust the field location

The fourth tab is reserved for the General properties, so you cannot add your own parameter to it.

Adding pictures Add images to make your custom component easier to use. First create the image and save it as a bitmap file (file extension bmp) in the ..\Tekla Structures\\nt\bitmaps folder. To add the image to the custom component dialog box, edit the input file as shown below:


109

y = 100 x = 50 height = 75 width = 100

The first pixel in the top left corner of a bitmap must be the same color (gray) as the background of the dialog box.

Preventing modifications Once the dialog box is ready, you can make the input file read-only to prevent accidental modifications. If the input file is not read-only, and someone else updates the custom component in the custom component editor, all your modifications to the input file will be lost. To make the input file read-only: 1. 2. 3.

In Windows Explorer, browse to find the input file. Right-click the file and select Properties... . Select the Read-only checkbox.

When an input file is read-only, and you try to update the custom component, Tekla Structures displays a warning message saying that the *.inp file is read-only and changes to it will not be saved. You have the following options:

• •

110


Click Cancel to return to the custom component editor. Click Continue to skip updating the *.inp file, but make all the other updates.

Using a custom component To use a custom component in a model: 1. 2. 3. 4. 5.

Use the keystrokes Ctrl + F to open the Component catalog dialog box. In the Search results list box, select Custom. Tekla Structures lists all custom components in the bottom pane. Double-click a custom component in the list to open it’s properties dialog box. Enter the properties you want to use and click Apply. Tekla Structures prompts you to pick the parts or points and parts needed to create the component.

Managing custom components Use the Component catalog to manage custom components. To open the Component catalog, use:

•

keystrokes Ctrl + F or

•

the Find a component icon on a components toolbar


111

To find all custom components, select Custom in the Search result list box All custom components have the Number -1 To view the properties of a custom component, double-click its name

Exporting and importing You can export custom components to a file, and then import the file into another model. Exporting

To export custom components to a file: 1. 2. 3.

Importing

Select the custom components in the component catalog. Right-click and select Export.... The Export components dialog box opens. Enter a name for the file in the Selection field. By default, the file extension is .uel and the file is located in the current model folder.

Tips on working with custom components These tips will help you to efficiently create, save, and share parametric and non-parametric custom components: General

Use library profiles when possible. So you do not have to copy user-defined profiles when you copy the component to other locations. Use short, logical names. Use the description field to describe the component and explain what it does. Store custom components together. It makes them easy to find and export. Consider creating a component model. Use this model to create and test custom components. Provide essential information. If you distribute your component to other users, remember to list the profiles it works with. Remember to copy user-defined profile cross sections with your custom component.

Creating nonparametric components

Use the simplest part you can. For example, if all you need is a rectangular shape, use a rectangular plate, not a contour plate. Rectangular plates only have 2 handles, so you only need to create a few bindings or magnetic planes to manipulate them. Contour plates require more because they have 4 chamfers and handles, when you set the advanced option XS_DRAW_CHAMFERS_HANDLES to CHAMFERS or HANDLES.

Rectangular plate Contour plate Only model parts as accurately as you need. If the only part information required is a part mark on the GA drawing and a quantity on the materials list, create a simple bar or plate. If, later, you need to include it in a detailed view, simply re-model the part more accurately. Creating intelligent (parametric) components

Plan to use magnetic planes to bind objects together. This makes intelligent components simpler, and easier to use, because it reduces the number of dimensions and parameters the user must enter. Model as many parts on the same plane as you can, and then use offsets to position them accurately.


115

Not using magnetic planes: Pick all 10 handles to bind the parts together Using 3 magnetic planes: Pick 3 points to bind the parts together (pick 1 point on each magnetic plane) Model embeds as custom parts and include them in components. Create simple components for specific situations. It is faster and easier to model simple components. They are also much easier to use. Avoid creating a ’super’ component to use in every possible situation.

Select a plane type from the Custom component toolbar. Move the mouse cursor over a component view. Tekla Structures highlights the available planes.


Construction plane Synopsis

126

This command creates a construction plane. If the plane is magnetic, the objects directly on it move with the plane.



You may occasionally need to define your own planes. For example, when you create special model parameters for floor height, building width, etc. Magnetic planes are also useful. You can use them to bind and move groups of objects. Rather than binding lots of handles and chamfers to faces, simply create a user plane that goes through all the handles and chamfers. Then make this plane magnetic and bind the plane to the appropriate face. When you move the plane, the attached handles and chamfers move with it. The custom component editor contains many default planes, for more information see Plane types (p. 125).

Usage

To add a construction plane: 1. 2. 3.

Click the Create construction plane icon. Pick four points. Click the middle mouse button. Tekla Structures draws the plane.

4.

Double-click the plane in the model. The Construction plane properties dialog box appears. Type a name for the plane. Select Magnetic, if you want Tekla Structures to bind touching objects to the plane. When you move a magnetic plane, objects directly on that plane automatically move with it.

5. 6.

Tekla Structures only binds objects to the plane whose reference points are directly on the plane. By default the magnetic distance is 0.05 mm. To change this use the variable XS_MAGNETIC_PLANE_OFFSET.

Introduction

Reinforcement

Once you have created a model of concrete parts, you will need to reinforce the parts. This chapter explains how to create reinforcement in Tekla Structures. It also includes a general description of reinforcement properties and an overview of reinforcement commands.

Audience

This chapter is aimed at concrete detailers and designers.

Assumed background

Before you start to create reinforcement, you need to have concrete parts in your model, as explained in Concrete Detailing. Running the structural analysis as explained in Analysis and Design gives you the required area of reinforcement. Read Loads for instructions on how to create loads.

See also

Numbering reinforcements

3.1 Getting started with reinforcement In Tekla Structures, you can use different methods to create reinforcement. You can create:

• • • • Concepts

Single reinforcing bars Reinforcing bar groups Reinforcement meshes Reinforcement components.

We recommend that you use reinforcement components to create reinforcement whenever possible. They are adaptive, attached to a concrete part, and updated automatically if the dimensions of the reinforced part change, for example. Then create additional reinforcing bars using other tools. Reinforcing bar groups consist of several identical, or very similar, bars. Tekla Structures

always treats these bars as a group, modifies them in the same way, deletes them all at the same time, etc. Reinforcement meshes include bars in two perpendicular directions, i.e. main bars and

crossing bars. Tekla Structures treats mesh bars as one unit but distinguishes the main and crossing bars.

TEKLA STRUCTURES 17 Reinforcement

133

Reinforcement properties

Every reinforcement object has properties which define it (for example, grade, diameter or size, minimum bending radius). Use the reinforcement properties dialog boxes to view or modify the properties of reinforcement. Click Detailing > Properties > Reinforcement to open reinforcement properties dialog boxes, or double-click an existing reinforcement object in the model.

Filtering by properties

You can use reinforcement properties in filters. For example, you can select, modify, or hide reinforcing bars based on their properties.For more information, see Filtering objects.

In reports and drawings

You can include reinforcement properties and user-defined attributes in drawing and report templates.

See also

Basic reinforcement properties (p. 134) Getting Started (p. 9) with Detailing

3.2 Basic reinforcement properties This section explains properties that are common to most types of reinforcement in Tekla Structures. Name

You can enter names for reinforcing bars. Tekla Structures uses names in reports and drawing tables.

Grade

The strength of the steel used in reinforcing bars. Can also indicate other factors, such as the weldability or surface deformations of the bar.

Size

Depending on the environment, the nominal diameter of the bar, or a mark that defines the diameter.

Bending radius

Complies with the design code you are using. Main bars, stirrups, ties, and hooks usually have their own minimum internal bending radii, which are proportional to the diameter of the reinforcing bar. The actual bending radius is normally chosen to suit the size of the mandrels on the bar-bending machine.

Bending types

Tekla Structures reinforcing bar bending types are recognized using internal bending type definitions. Internal bending types are hard coded to the software. However, these internal bending types are mapped to area specific reinforcing bar bending type codes in the rebar_schedule_config.inp file in the ..\Tekla Structures\\environments\\system\ folder. This file can be localized to match local requirements. For more information on internal bending types, see Reinforcing bar bending types (p. 167).

Reinforcement catalog

Grade–size–radius combinations are predefined in the reinforcement catalog. You can select which catalog to use, and add, modify, and delete the information it contains. See The reinforcing bar catalog.

Select...

To define the grade, size, and bending radius of a reinforcing bar, click Select... next to the Grade, Size, and Bending radius fields in the Reinforcing bar properties dialog box. The Select reinforcing bar dialog box appears, showing the available bar sizes for the chosen grade. You can also define whether the bar is a main bar or a stirrup or tie:

134


You can also enter the grade, size, and bending radius of individual reinforcing bars using the appropriate fields in the Reinforcing bar properties dialog box.

Class

Use Class to group reinforcement. To display reinforcing bars of different classes in different colors, click View > Representation > Object Representation... and select Color by class from the Color list box. For more information, see Color settings for parts.

Bar groups

Reinforcing bar groups mainly have the same properties as single reinforcing bars. They can also have the following extra properties:

• • • See also

Number of bars Spacing (see Spacing reinforcing bars (p. 138)) Tapering (see Tapered bar group (p. 157))

Hooks (p. 135) Concrete cover (p. 137) Spacing reinforcing bars (p. 138) Omitting reinforcing bars (p. 138) User-defined attributes of reinforcement (p. 139) Meshes (p. 139) Numbering reinforcements

Hooks To add hooks to the ends of reinforcing bars for anchoring purposes, use the Hooks section of the Reinforcing Bar Properties dialog box, or the Hooks tab in the Reinforcement Mesh Properties dialog box:


135

The options for the hook at the beginning and end of the bar are:

Option

Description No hook Standard 90-degree hook Standard 135-degree hook Standard 180-degree hook Custom hook

The reinforcement catalog contains predefined dimensions for all standard hooks (minimum bending radius, minimum hook length). See The reinforcing bar catalog. Custom hook

To manually define the angle, radius, and length of a hook, select the Custom hook option and enter values to the following fields in the Reinforcing Bar Properties dialog box:

Field

Description

Angle

Enter a value between – 180 and +180 degrees.

Radius

Internal bending radius of the hook. Use the same radius for the hook and for the reinforcing bar. If the hook and the reinforcing bar have different radiuses, Tekla Structures does not recognize the shape of the reinforcing bar.

Length

Length of the straight part of the hook. If the length is set to zero, no hooks are created.

136


Angle Radius Length

Concrete cover Reinforcing bars need a concrete cover, to protect them against harmful elements, such as the weather and fire. When you create single bars, Tekla Structures uses the thickness of concrete cover to determine the position of the bar. You pick points to define the shape and plane of the bar. Cover thickness

Use the Cover thickness fields in the reinforcement properties dialog boxes to define concrete cover.

Example

To create a beam stirrup, pick the corner points on the cross-sectional end plane of the beam to define the bar shape and plane. The cover thickness on the plane is the distance from beam’s bottom, top, and side surfaces to the stirrup. The cover thickness from the plane is the distance from the end surface of the beam to the stirrup, and perpendicular to the bar plane.

Concrete cover

Description Concrete cover on the plane For example, the distances from a beam’s bottom, top, and side surfaces to a stirrup. To specify different concrete covers on the different legs of a reinforcing bar, enter a thickness value for each leg in the On plane field, in the order you pick points to create the bar. If you enter less values than there are bar legs, Tekla Structures uses the last value for remaining legs. Concrete cover from the plane For example, the distance from a beam’s end surface to the closest stirrup, perpendicular to the stirrup plane.

Leg length

At the start and end point of a reinforcing bar, you can also define the concrete cover in terms of cover thickness or leg length.

Option

Description Cover thickness

Defines the distance from the bar end to the concrete surface.

Leg length

Defines the length of the ultimate leg of the bar.

To define the length of an ultimate leg of a bar, use the Leg length option and the Snap to nearest points switch. Then pick anywhere on a part edge or line to indicate the direction for the bar leg.

Reinforcement components

When you use reinforcement components, Tekla Structures places the reinforcement using the dimensions of the part and the values in the Cover thickness field, or the graphic fields shown below:

Spacing reinforcing bars Bar groups

There are several ways to distribute bars in a reinforcing bar group. To create a bar group, open the Reinforcing Bar Properties dialog box. On the Group tab, select an option from the Creation method list box. The options are:

See also

Option

Description

By exact spacing value with flexible first space

Creates fixed, equal spaces between the bars. The first space adjusts to even out bar distribution. Enter the spacing value in the Exact spacing value field. If the first space is less than 10% of the exact spacing value, Tekla Structures removes one bar.

By exact spacing value with flexible last space

Same as the first option, but the last space adjusts to even out bar distribution.

By exact spacing value with flexible middle space

Same as the first option, but the middle space adjusts to even out bar distribution. If there are an odd number of bars (two middle spaces), the other middle space adjusts to even out bar distribution.

By exact spacing value with flexible first and last space

Same as the first option, but both the first and last spaces adjust to even out bar distribution.

By exact spacings

Distributes the bars using the information you specify in the Exact spacing values field, so you can enter every spacing value manually. Use the multiplication character to repeat spacings, e.g. 5*200, to create five spaces of 200.

Equal distribution by number of reinforcing bars

Tekla Structures determines the spacing value based on the fixed number of bars. Enter the number in the Number of reinforcing bars field.

Equal distribution by target spacing value

Tekla Structures aims the spacing value as closely as possible at the value in the Target spacing value field and determines the number of bars compatibly.

Omitting reinforcing bars (p. 138)

Omitting reinforcing bars You may occasionally need to omit specific reinforcing bars. For example, when several reinforced areas intersect, causing reinforcing bars to overlap, or when you want to start bar distribution at a specific distance from the end of a part. To indicate which bars to omit, select an option from the Reinforcing bar(s) not to be created to the group list box:

User-defined attributes of reinforcement Create user-defined attributes to add information about reinforcing bars, bar groups, or reinforcement meshes. Attributes can consist of numbers, text, or lists. To create user-defined attributes, click the User-defined attributes button in the reinforcement properties dialog box. Use the User field 1...4 fields to define the attributes you need. You can also change the name of these fields, and add new ones, by editing the objects.inp file. For more information, see Adding properties.

Meshes A reinforcement mesh consists of reinforcing bars in two directions. You can define the following properties.

Diameter 2 Spacing 2 Overhang Spacing 1 Diameter 1 Length Overhang Width Create mesh

Create mesh using the Detailing > Create Reinforcement > Reinforcement Mesh command or a component.

Mesh shape

Reinforcement meshes can be:


139

• • • Distribution pattern of bars

Rectangular Polygonal Bent

You can create meshes with unevenly-spaced bars. You can also define a different bar size or multiple different bar sizes for the longitudinal bars and the crossing bars. Multiple bar sizes enable pattern creation. For example, if you enter bar diameters 20 2*6 in the longitudinal direction, Tekla Structures creates a pattern with one size 20 bar and two size 6 bars. This pattern can be repeated in the mesh along the longitudinal direction.

For more information, see Customizing reinforcement meshes (p. 151). Mesh size

The way you define the size of the mesh depends on the shape of the mesh and how it was created:


Evenly-spaced rectangular meshes - manually define the size Polygonal and bent meshes - Tekla Structures automatically calculates the width and length Unevenly-spaced meshes - Tekla Structures calculates the size of the mesh using the values in the Distance(s), Left overhang, and Right overhang fields.

Add bar corners Remove bar corners Move bar and mesh corners Add points to reinforcing bars, bar groups, and bent meshes


141

• • •

Remove points from reinforcing bars, bar groups, and bent meshes Change the direction of the longitudinal mesh bars Change the distribution length of bar groups

Using reinforcement handles Tekla Structures uses handles to indicate:

• • •

The ends and corners of a reinforcing bar The distribution length of a bar group The corners and main bar direction of a mesh

When you select a reinforcement, the handles turn magenta. Examples

Here are some ways to use handles to modify reinforcement:

Handles to change group distribution length Handles to move bar corners

142


Handles to move mesh corners Handles to change main bar direction To use handles to modify reinforcement: 1. 2. 3.

Select the reinforcement to display its handles. Click the handle you want to move. Tekla Structures highlights the handle. Move the handle(s) like any other object. If Drag and drop is active, just drag the handle to a new position.

For more information, see Moving an object, Moving an object using drag-and-drop and Polygon cuts.

Using adaptivity Reinforcements follow the shape of the part also when their handles are located on the face or edge of the part. The following types of adaptivity are available:

• •

Fixed adaptivity: handles retain their absolute distances to the nearest part faces. Relative adaptivity: handles retain their relative distances to the nearest part faces in relation to the part’s overall size.

To modify the general adaptivity settings, go to Tools > Options > Options... > General. You can modify the adaptivity settings for each part separately. These modifications override the general settings. Example

Grouping reinforcements You can group single reinforcing bars and reinforcing bar groups. Only reinforcements where each reinforcing bar is in one plane can be grouped. All groups are created with exact spacings. Single reinforcing bars need to have the same bending shape. To group single reinforcing bars or reinforcing bar groups: 1. 2. 3. 4.

Click Detailing > Create Reinforcement > Group. Select all the reinforcing bars or reinforcing bar groups that you want to group. Click the middle mouse button. Select one reinforcing bar or reinforcing bar group to copy the properties from. The new group gets the same properties as the selected reinforcing bar.

The reinforcing bar or reinforcing bar group that you copy the properties from is also added to the group. This means, for example, that you cannot copy properties from a separate reinforcing bar group which you do not want to include in your new reinforcing bar group. Limitations

You cannot create circular or curved reinforcing bar groups by grouping.

Exploding reinforcement Before you can modify or remove single bars in a reinforcement component, you need to use the Explode Component command to ungroup the bars that the reinforcement contains. To ungroup reinforcing bars: 1. 2.

150


Click Detailing > Component > Explode Component. Select the blue modeling tool symbol (M) on the reinforcement. Tekla Structures ungroups the reinforcing bars.

Reinforcement geometry validity Reinforcement creation or modification can result in invalid reinforcement geometry. For example, too big bending radius can cause invalid reinforcement geometry. The invalid geometry is visualized in the model. Tekla Structures displays a warning message, and draws a thin line between the reinforcement handles to show the invalid geometry. You can correct the reinforcement geometry by selecting the line and modifying the reinforcement properties. You can check the reinforcement geometry validity by running the command Tools > Diagnose & Repair Model > Dianose Model. The report lists the reinforcements with invalid geometry. If a model contains reinforcements with invalid geometry, the reinforcements are not shown in the drawings. The reinforcements become visible when the geometry is corrected. Limitations

Reinforcement geometry validity check does not work with circular or curved reinforcing bar groups.

Conceptual reinforcements Conceptual reinforcements can be created only with Steel Detailing, Reinforced Concrete Detailing and Engineering configurations. Engineers or detailers can model conceptual reinforcements that show the geometry of the reinforcements. Conceptual reinforcements look similar to detailed reinforcements but do not include the option to perform numbering. When you create a conceptual reinforcement, Tekla Structures displays a warning message noting that you cannot number the reinforcement. You can use the Inquire command to check whether the reinforcement is conceptual or detailed. Conceptual reinforcements can be converted to detailed reinforcements. You can convert individual conceptual reinforcements to detailed reinforcements in Full, Precast Concrete Detailing and Reinforced Concrete Detailing configurations. Detailed reinforcements can be converted to conceptual reinforcements in Steel Detailing and Engineering configurations. Modifying part properties does not automatically convert a detailed reinforcement to a conceptual one, or vice versa. For example, if you use the Engineering configuration and modify the model, detailed reinforcements do not convert back to conceptual reinforcements. See also

Converting conceptual reinforcements to detailed reinforcements (p. 151)

Converting conceptual reinforcements to detailed reinforcements Individual conceptual reinforcements that have been created with Steel Detailing or Engineering configuration can be converted to detailed reinforcements in Full, Precast Concrete Detailing, and Reinforced Concrete Detailing configurations. To convert conceptual reinforcements to detailed reinforcements: 1. Select the reinforcement. 2. Right-click and select Convert to detailed reinforcement. If you want to convert detailed reinforcements to conceptual reinforcements in Engineering or Steel Detailing configuration, right-click and select Convert to conceptual reinforcement. See also

Property

Description

Spacing method

Defines how the mesh bars are distributed. The options are:

•

Same distance for all: Use to create meshes with

evenly-spaced bars. Tekla Structures distributes as many bars as possible for the length of Length or Width, using the Distance(s) and Left overhang values. The Right overhang is calculated automatically, and it cannot be zero.

•

Multiple varying distances: Use to create meshes with

unevenly-spaced bars. Tekla Structures calculates the Width and Length based on the Distance(s), the Left overhang and the Right overhang values. If you do not change any of the values, the spacing method changes back to Same distance for all. Distance(s)

Spacing values of longitudinal or crossing bars. If you select the Multiple varying distances spacing method, enter all spacing values, separated by spaces. You can use multiplication to repeat spacing values. For example: 2*150 200 3*400 200 2*150

Left overhang Right overhang

Extensions of longitudinal bars over the outermost crossing bars. Extensions of crossing bars over the outermost longitudinal bars.

Diameter

Diameter or size of longitudinal or crossing bars. You can define multiple diameters for the bars in both directions. Enter all the diameter values, separated by spaces. You can use multiplication to repeat diameter values. For example, 12 2*6 in longitudinal direction and 6 20 2*12 in crossing direction.

Reinforcing bar bending types

Tekla Structures recognizes different reinforcing bar bending shapes and assigns bending type identifiers to them. The table below lists these reinforcing bar bending types. If Tekla Structures does not recognize the shape of a reinforcing bar, it assigns the UNKNOWN bending type to it. The bending type identifiers in the table below are internal, hard-coded types of Tekla Structures. The leg dimensions (D1, D2, etc.) and bending angles (A1, A2, etc.) of reinforcing bars are internal dimensions and angles. You can map internal types, for example, to countryor project-specific types, and internal dimensions and angles to specific template attributes. You do this in the rebar_schedule_config.inp file. See Reinforcement in templates (p. 188). Reinforcing bar bending dimensions are calculated so that the leg dimensions (D1, D2, etc.) follow the outer edge, or the edge extension, of the reinforcing bar. The total length is calculated according to the center line of the reinforcing bar. The magenta points in the images represent the points you pick in the model when you create reinforcing bars.

4.1 Reinforcement in templates Audience

This topic is aimed at Tekla Structures users who need to localize reinforcing bar bending types or to create templates for reinforcing bar bending schedules.

Reinforcement templates

You can show dimensions, bending angles, and bending types of reinforcing bars in drawings and reports by including reinforcement-specific attributes, such as DIM_A, ANG_S, SHAPE, and SHAPE_INTERNAL, in template fields. For more information on creating templates, see the Template Editor (TplEd) online help.

Mapping dimensions

Use the rebar_schedule_config.inp file in the ..\Tekla Structures\\environments\\system folder to map:

• •

Tekla Structures internal reinforcing bar dimensions and angles with specific template attributes Tekla Structures internal reinforcing bar bending types with specific bending types

These mappings are environment-specific by default. You can modify them to suit your company or project needs. You can use equations, functions, and if statements to calculate the dimensions and angles you need to show.

188


Use any standard text editor (for example, Notepad) to edit the rebar_schedule_config.inp file. Examples

The following example of the rebar_schedule_config.inp file maps the internal bending type 5_1 to the bending type identifier E, and the leg dimensions and bending angles to specific template attributes:

rebar_schedule_config.inp (Example 1) BEND_TYPE_5_1[1]="E" BEND_TYPE_5_1[2]="DIM_A=D1" BEND_TYPE_5_1[3]="DIM_B=D5" BEND_TYPE_5_1[4]="DIM_C=D2" BEND_TYPE_5_1[5]="DIM_TD=TD" BEND_TYPE_5_1[6]="ANG_U=A1" BEND_TYPE_5_1[7]="ANG_V=A2"

With this mapping, the internal bending type 6_2 becomes XY, and the template attributes DIM_B and DIM_C will show the horizontal and vertical dimensions of the second leg D2, and DIM_E and DIM_F the horizontal and vertical dimensions of the fourth leg D4:

rebar_schedule_config.inp (Example 2) BEND_TYPE_6_2[1]="XY" BEND_TYPE_6_2[2]="DIM_A=D1" BEND_TYPE_6_2[3]="DIM_B=D2*COS(A2*PI/ 180)" BEND_TYPE_6_2[4]="DIM_C=D2*SIN(A2*PI/ 180)" BEND_TYPE_6_2[5]="DIM_D=D3" BEND_TYPE_6_2[6]="DIM_E=D4*COS(A1*PI/ 180)" BEND_TYPE_6_2[7]="DIM_F=D4*SIN(A1*PI/ 180)" BEND_TYPE_6_2[8]="DIM_G=D5" BEND_TYPE_6_2[9]="DIM_TD=TD"

The following example maps the internal bending type 4 to the bending type identifier A if the dimensions D1 and D3 are the same. Otherwise it maps 4 to B:

rebar_schedule_config.inp (Example 3) BEND_TYPE_4[1]=if (D1==D3) then ("A") else ("B") endif BEND_TYPE_4[2]="DIM_A=D1" BEND_TYPE_4[3]="DIM_B=D2" BEND_TYPE_4[4]="DIM_C=D3" BEND_TYPE_4[5]="DIM_TD=TD"

If Tekla Structures does not recognize a reinforcing bar bending shape, it uses the internal bending type UNKNOWN for it. In the rebar_schedule_config.inp file you can also define how unknown bending types appear in drawings and reports. For example, you may just want to use the bending type identifier ???, and list all leg dimensions and bending angles:


189

rebar_schedule_config.inp (Example 4) BEND_TYPE_UNKNOWN[1]="???" BEND_TYPE_UNKNOWN[2]="DIM_A=D1" BEND_TYPE_UNKNOWN[3]="DIM_B=D2" BEND_TYPE_UNKNOWN[4]="DIM_C=D3" BEND_TYPE_UNKNOWN[5]="DIM_D=D4" BEND_TYPE_UNKNOWN[6]="DIM_E=D5" BEND_TYPE_UNKNOWN[7]="DIM_F=D6" BEND_TYPE_UNKNOWN[8]="ANG_S=A1" BEND_TYPE_UNKNOWN[9]="ANG_T=A2" BEND_TYPE_UNKNOWN[10]="ANG_U=A3" BEND_TYPE_UNKNOWN[11]="ANG_V=A4" BEND_TYPE_UNKNOWN[12]="DIM_TD=TD"

User-defined reinforcing bar bending shapes

You can define your own custom reinforcing bar bending shapes with the Rebar shape manager tool, and thus increase the amount of recognised reinforcing bar shapes. Custom bending shapes are useful when Tekla Structures does not recognize a reinforcing bar bending shape and assigns it UNKNOWN bending type. The custom bending shapes can be used in bending schedules and pull-out pictures in the same way as the predefined, Tekla Structures internal bending shapes. You can also import and export the custom bending shapes. When you define your custom shapes, an XML file called RebarShapeRules.xml is created in the currect model folder. By default, Tekla Structures installation package already contains an XML file called RebarShapeRules.xml. The file is located in ..\Tekla Structures\\environments\\system folder, and it contains the most typical reinforcing bar shapes of your environment. These catalog shapes can be appended with your custom shapes.

Defining your own custom bending shapes is meant for advanced users.

4.

Click Run. Rebar shape manager opens, and lists the selected reinforcing bars in the Model rebars list. The Model rebars list shows the ID number and the bending shape code of the reinforcing bars. The Catalog shapes list shows the shapes that exist in the RebarShapeRules.xml file.

Alternatively, you can first open Rebar shape manager and then select reinforcing bars in the model. Click Get selected to add the reinforcing bars to the Model rebars list.

5. 6.

Select one unknown shape from the Model rebars list. Define the needed bending shape information. • Use the Shape code box to enter a shape code for an unknown shape.

•

Bending shape rules lists the rules for the bending shape. You can add or a delete a rule by clicking the Add and Delete buttons. If you modify the Bending shape rules, the Reset button restores the original rules.

•

Select the Require hooks check box if you want to define different shape codes for two bars that otherwise have exactly the same geometry, but the other bar has hooks and the other one does not have hooks. By default, the hooks are not required and the check box is not selected. Use Bending schedule fields to define the content for a bending schedule. Rightclick a field to select the shape properties, or to enter a formula. If you have already defined the shape code for the selected reinforcing bar but have modified the shape code, bending shape rules or the bending schedule field definitions, click Update to update the existing shape code definition.

• •

The names of the Bending schedule fields (A, B, and so on) are used in templates and reports. To make sure that also old reports work corrcetly, we recommend that you use the same DIM_XX fields as used in the rebar_schedule_config.inp file. 7.

When you have finished defining the new shape, click Add to add the bending shape definition to the RebarShapeRules.xml file. To enable the Add button you need to change the bending shape rule, enter a shape code or require the hooks.

8.

Click Save to save the RebarShapeRules.xml file. By default, the file is located in the current model folder. Next time you create, for example, a bending schedule, Tekla Structures uses the updated bending shape information and recognizes the added bending shape and assigns a correct bending shape code to it.

Modeling direction

When the reinforcing bar shape is being defined, the start or end of the modeling direction is always sorted based on the bending angles and/or leg lengths. This means that the shape code will be the same regardless of the modeling direction. Bending radius is not taken into consideration in the sorting, and therefore it cannot be trusted that radius 1 is always less than radius 2 or vice versa.

5.2 Defining rules for reinforcing bar bending shapes manually In some cases, the reinforcing bar bending shape rules defined by Rebar shape manager are not sufficient to distinguish certain bending shapes. In such situations, you can add new bending shape rules manually. To define a reinforcing bar bending shape rule manually: 1.

Click the Add button next to the Bending shape rules list. The New bending rule dialog box opens.

2.

Select the options from the lists to define the new rule. The content of the lists depends on the shape and the bendings of the reinforcing bar.

3.

Click OK to add the new rule to the Bending shape rules list. The OK button is enabled only when the rule is valid.

Defining additional rules for bending shapes is meant for advanced users.
