To eliminate the repetitive listing of the various elements that require consideration of expected strength or overstrength, AISI S400-20 defined “capacity protected components.” Section B3 provides the design requirements for these components. Each SFRS has its own list of capacity protected components. For example, for wood structural panel shear walls, Section E1.4.1.2 lists the capacity protected components. The Commentary for Section E1.4.1.2 also discusses “Capacity Protected Components.”

Although, not based on AISI S400-20, AISI D113-19, Cold-Formed Steel Shear Wall Design Guide, illustrates the design procedure for the consideration of expected strength and overstrength. Determination of the overstrength factor, Ω_E, is updated in S400-20, but application of the factor is as illustrated in D113-19.

 

SFIA Receives ANSI Accreditation

On July 2, 2024, the Executive Standards Council of the American National Standards Institute, ANSI®, has approved the accreditation of the Steel Framing Industry Association (SFIA). As an ANSI-accredited standards development organization. SFIA assumes the management of certain cold-formed steel (CFS) framing standards previously managed by the American Iron and Steel Institute. These CFS standards will be governed by the newly formed SFIA Standards Committee and managed by SFIA Canvass Groups.

The CFSEI Hotline from the Cold-Formed Steel Engineers Institute receives inquiries about cold-formed steel (CFS) applications. Architects, engineers, building officials, students and contractors needing answers from respected experts can check “Ask an Expert” on the CFSEI website or call 1-800-79STEEL.

CFSEI is part of the Steel Framing Industry Association (SFIA), where its leadership as the industry’s key touchpoint for CFS design receives full support.
