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.

Disclaimer: Designs cited herein are not intended to preclude the use of other materials, assemblies, structures or designs when these other designs demonstrate equivalent performance for the intended use. CFSEI documents are not intended to exclude the use and implementation of any other design or construction technique.
