Cold-formed steel structural members are commonly subjected to torsion. The torsional behavior of open cross-sections can be complex, involving both warping torsion and St. Venant torsion. Most structural engineering curriculums do not teach this combined torsion response, leaving many engineers with limited ability to properly design for torsion. To complicate matters, most structural analysis software does not fully capture the torsional behavior for cold-formed steel members.

This webinar will review some torsion fundamentals and explain torsion distribution using analogies to flexural behavior familiar to structural engineers. The similarity to flexure will be demonstrated using the CFS® software. The AISI design provisions for combined bending and torsion will be reviewed, and the application of these provisions will be evaluated with several design examples.

Presenter: Bob Glauz, P.E., MSCE

Bob Glauz is the author of the CFS® software used internationally for cold-formed steel design. He is a member of the American Iron and Steel Institute (AISI) Committee on Specifications and chairs the AISI Committee on Member Design. He is also a member of the ASCE/SEI Standards Committee on Stainless Steel Cold-Formed Sections, the Structural Stability Research Council (SSRC) and the SSRC Task Group on Stability of Steel Members. Bob has authored several technical articles on lateral-torsional, flexural-torsional, and distortional buckling of cold-formed steel members.
