Tech Note L400-25: Non-Bearing Cold-Formed Steel Lateral Force Resisting Systems

Summary: Cold-formed steel (CFS) lateral systems are commonly used in bearing wall systems buildings, but non-bearing CFS lateral force resisting systems are non-standard applications that fall outside of ASCE/SEI 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, design criteria, and pose significant challenges for design and construction. These walls can offer lateral load resistance but come with limitations that require intensive detailing. Specifiers and designers must understand these systems performance, limitations, and detailing options for proper force transfer. This Tech Note covers the limitations, alternative solutions to avoid the unnecessary use of non-bearing lateral force resisting systems, and critical detailing practices when they are used.
