Course Description June 3, 2013– Fundamentals Fundamentals of Stability for Steel Steel Design: Course Course Introduction and Behavior of Compression Members This lecture will begin with a brief overview of the 8-lecture course. The beha behavi vior or of comp compre ress ssio ion n memb member erss will will then then be cov covered ered.. The The assu assump mpti tion onss in the solution to the Euler column problem will be used as a basis for syst system emat atic ical ally ly movi moving ng from from the the theo theore reti tica call solu soluti tion on pres presen ente ted d in 1757 1757 to the the modern day methods of design and analysis of compression members. Emph Emphas asis is will will be plac placed ed on the the eff effects ects of mate materi rial al yiel yieldi ding ng acce accent ntua uate ted d by the the pres presen ence ce of resid esidua uall stre stress sses es,, init initia iall impe imperf rfec ecti tion onss and and end end cond condit itio ions ns.. The The flexural buckl ckling strength of members without slender elements will be cove covere red d and and ulti ultima mate tely ly pres presen ente ted d in the the form form of colu column mn curv curves es.





Learning Objectives • Gain familiarity with stability and steel structures. • Learn and understand the assumptions in the Euler column solution.

• Become familiar with the effects of bending on the strength of a column.

• Learn and understand the effects due to residual stresses, initial imperfections and end conditions.

Session 2: June 10 – Design of Compression Members by P.S. Green, PE, PhD Initially, an overview of flexural, torsional, and flexural-torsional resistance of individual column members will be provided. Emphasis then will be placed on defining and assessing the AISC LRFD and ASD strengths of various structural shapes, including wide flange, round and square HSS, cruciform, equal and unequal single and double leg angles, WT, channel, and built-up shapes.
