Presentation Outline

What can be done when a structural member requires a high-load capacity? The common solution is to design a built-up profile consisting of two or more cold-formed steel (CFS) framing sections. Built-up profiles use common CFS framing members, such as shear wall boundary studs, floor joists, stud packs and headers. This webinar will review the applicable AISI S100, North American Specification for the Design of Cold-Formed Steel Structural Members and AISI S240, North American Standard for Cold-Formed Steel Structural Framing design provisions for two types of built-up profiles — built-up compression members and built-up flexural members. The webinar will review the member limit states of global buckling, local buckling and distortional buckling. It will also provide guidance for achieving adequate interconnection of the individual profiles.
