The Cold-Formed Steel Engineers Institute (CFSEI) will host a webinar on “Demystifying Cold-Formed Steel Torsion Analysis for Design” on Thursday, October 29, 2020 from 3:00 p.m. to 4:30 p.m. EDT. The webinar is designed for architects, engineers, building officials and contractors. Participants are eligible for 1.5 PDHs.

The webinar will address the torsional behavior of open cross-sections, which 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 American Iron and Steel Institute (AISI) design provisions for combined bending and torsion will be reviewed, and the application of these provisions will be evaluated with several design examples.
