The Cold-Formed Steel Engineers Institute (CFSEI) has published Technical Note L101-23, “Design of Cold-Formed Steel Sheet and Wood Structural Panel Sheathed Shear Walls for Wind and Seismic Forces.”
Tech Note L101-23 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. It presents a basic overview of design considerations, sample shear wall capacity and loading comparisons. For detailed design examples, refer to the AISI D113-19.
- Tech Note L101-23 is free of charge to CFSEI Corporate, Professional and Student Members
- For nonmembers, Tech Note L101-23 is available for purchase at CFSEI On-Demand
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.
Part of the front cover of CFSEI Technical Note L101-23, “Design of Cold-Formed Steel Sheet and Wood Structural Panel Sheathed Shear Walls for Wind and Seismic Forces.”
Tech Note L101-23 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.
CFSEI Technical Notes are produced and updated by industry experts to educate design professionals on advancements and best practices in CFS design and construction.
Cold-Formed Steel Engineers InstituteThe Cold-Formed Steel Engineers Institute (CFSEI) comprises hundreds of structural engineers and other design professionals who are finding a better way to produce safe and efficient designs for commercial and residential structures with cold-formed steel.
CFSEI members work together to develop and evolve industry standards and design methods, produce and issue technical bulletins, and provide seminars and online training to improve the knowledge and skills base of engineers and design professionals. For more information, visit www.cfsei.org.
On May 1, 2023, CFSEI moved from the American Iron and Steel Institute to its new home with the Steel Framing Industry Association (SFIA), where the CFSEI’s leadership and goals will continue to be supported in its role as the industry’s key touchpoint for CFS design.
