Tech Note L101-23: Design of Cold-Formed Steel Sheet and Wood Structural Panel Sheathed Shear Walls for Wind and Seismic Forces

Summary: This Technical Note provides an overview of low seismic and wind-controlled steel sheet and wood structural panel sheathed cold-formed steel (CFS) framed shear wall designs. It is a digest of the AISI D113-19, Cold-Formed Steel Shear Wall Design Guide and presents a more basic overview of design considerations. Sample shear wall capacity and loading comparisons are provided. For detailed design examples, refer to the AISI D113-19.

Code references are limited to AISI S240-15, North American Standard for Cold-Formed Steel Structural Framing; more detailed references, including AISI S400-15, North American Standard for Seismic Design of Cold-Formed Steel Structural Systems for high seismic design requirements can be found in the AISI D113-19.

This Technical Note is intended as a starting point for engineers requiring CFS framed shear wall design guidance and can be used to determine if review of additional discussion found in AISI D113-19 is warranted. For information on gypsum board sheathed shear walls and steel strap braced walls, refer to AISI S240-15 and S400-15. CFSEI Technical Note TN L001-10, Design of Diagonal Strap Bracing Lateral Force Resisting Systems for the 2006 IBC also provides strap braced wall analysis discussion.
