The Cold-Formed Steel Engineers Institute will host a webinar on “Cold-Formed Steel Strap-Braced Walls: AISI S213 to AISI S400” on June 12. The webinar is designed for architects, engineers, building officials and contractors. Participants are eligible for 1.5 continuing education hours.
A common means of constructing the lateral load-resisting system of cold-formed steel structures is to provide diagonal tension-only strap braces in the walls. The strap-braced walls act as a vertical concentrically braced system that transfers the lateral loads from the roof and floor levels to the foundation. Provisions for the design of strap-braced walls can be found in AISI S213-07, North American Standard for Cold-Formed Steel Framing – Lateral Design. A new standard is being developed to replace AISI S213 that will contain seismic-specific design requirements and recent research results. The new standard will be known as AISI S400, North American Standard for Seismic Design of Cold-Formed Steel Structural Systems.
