This is the new OneSteel/BHP web side plate connection, the principal reference for which is the OneSteel design booklet DB5.1, Design of the Web-Side-Plate Connection. For convenience, the publication is provided as an Acrobat PDF on the Limcon CD.
Flexible End Plate Connection You may check or design the flexible end plate connection for beam web, column flange, or column web support.
Angle Cleat Connection The angle cleat connection comprises angle cleats on one or both sides of the web of the supported member. Each cleat is bolted to both the supported and the support members.
Bolted Angle Seat Connection You can check or design many variations on the connection shown.
Welded Angle Seat Connection
You can check or design many variations on the connection shown.
Bearing Pad Connection You can check or design many variations on the connection shown.
Welded Beam/Column Connection You can check or design many variations on the connection shown. There may be a beam on one or both sides. Where a slope angle is specified it applies to both beams. Single or double web plate doublers are available as an alternative to shear (diagonal) stiffeners.
Bolted Moment End Plate Connection From the dialog box for the bolted moment end plate connection you can check or design any of the types shown below. There may be a beam on one or both sides. There may be either two or four bolts at the top and bottom flanges. For the Type A and B connections column flange doubler plates may be specified at the top, bottom, or full height. Single or double web plate doublers are available as an alternative to shear (diagonal) stiffeners.
TYPE A - END PLATE SQUARE TO BEAM
TYPE B - END PLATE NOT SQUARE TO BEAM
TYPE C - MATCHING MITRED END PLATES
TYPE C2 - APEX CONNECTION IN PORTAL FRAME
Haunched Beam End Plate Connection From the dialog box for the haunched beam end plate connection you can check or design either of the types shown below. The haunch tee is cut from the same section as the parent beam. There may be two or four bolts at each flange but at least one flange must have four bolts. For the knee connection there may be a beam on one or both sides. Single or double web plate doublers are available as an alternative to shear (diagonal) stiffeners.
TYPE A - APEX CONNECTION IN PORTAL FRAME

AISC Flush Moment End Plate Connection This connection is available for a limited range of WF and UB sections. There may be either 2 or 4 bolts at the tension flange. Click here for more information on the design model.
AISC Extended Moment End Plate Connection
This connection is available for WF and UB sections. Unstiffened connections are available with 4, 6, or 8 bolts at the tension flange. Those with 4 and 8 bolts at the tension flange are also available with a triangular stiffener outside the flange. Click here for more information on the design model.

(e) Multiple Row 1/3 Stiffened
Moment End Plate Connections for RHS/SHS
4-Bolt Moment End Plate Connection for RHS/SHS
8-Bolt Moment End Plate Connection for RHS/SHS These connections are available for RHS and SHS compact sections only. The design models, based on 2-dimensional yield line analysis, were developed in recent Sydney University research projects that included full-scale testing (see R745 and R827). Bolts must be high-strength tensioned bolts, such as 8.8/TB or A325PT. The design models are only valid for a combination butt/fillet weld of specified leg dimension all around the section.
Bolted Splice From the dialog box for the bolted splice you can check or design many variations on the basic connection type. Inner flange plates may be specified. The web splice may have one or two columns of bolts. When the gap between the members is zero it is assumed that the ends are prepared for full contact and compressive actions are carried in bearing on the contact surfaces.
FLANGE SPLICES BOLTED BOTH SIDES
COMBINATION BOLTED AND WELDED FLANGE SPLICES
Welded Splice Each flange splice for this connection comprises a full penetration butt weld while the web splice consists of web doubler plates on each side, welded all around with a continuous fillet weld.
Base Plate Limcon checks many kinds of base plate connection. The view below shows the base plate for a UB column - you can also check base plates for other I sections, channels, and hollow sections. Holding-down bolts may have an ordinary bolt head or a hook. There is no design function for the base plate connection.
HSS Cap Plate Connection
The design model for this connection permits a tension load on a column, which may be RHS, SHS, or CHS. The design model does not include compression because the connection components are minimally loaded by the bearing action of the column.
HSS Mitred Knee Connection This design model is available for SHS members RHS members whose widths are the same. The capacity of the connection is greater with the optional stiffening plate.
HSS Y/T Connection There are many possible configurations of this connection, one of which are shown below. The chord may be RHS, SHS, CHS, or an I section. The brace may be RHS, SHS, or CHS. Not all combinations of section types are permitted.
HSS X Connection There are many possible configurations of this connection, one of which are shown below. The chord may be RHS, SHS, CHS, or an I section. The brace may be RHS, SHS, or CHS. Not all combinations of section types are permitted.
HSS K/N Gap Connection There are many possible configurations of this connection, some of which are shown below. The chord may be RHS, SHS, CHS, or an I section. The braces may be RHS, SHS, or CHS. Not all combinations of section types are permitted.

K/N Overlap Connection with SHS Chord and Braces
Web Side Plate (Fin Plate) Connection You can check or design many variations on the connection shown. There may be one or two columns of bolts in the cleat. The support may be a beam web, a column web or flange, or a hollow section.
Web Side Plate II Connection This is the new OneSteel/BHP web side plate connection, the principal reference for which is the OneSteel design booklet DB5.1, Design of the Web-Side-Plate Connection. For convenience, the publication is provided as an Acrobat PDF on the Limcon CD.
