The American Society of Civil Engineers (ASCE) Specification for the Design of Cold-Formed Stainless Steel Structural Members was last updated in 2002 and significant advancements in research knowledge and companion design standards have occurred in the intervening 20 years. A dedicated group of volunteers re-formed the ASCE 8 specification committee and over the course of four years completely revamped the standard. The new version, ASCE 8–22, still parallels the cold-formed carbon steel standard AISI S100, and has improved and simplified design expressions for members and connections. Both the Continuous Strength Method and the Direct Strength Method are provided in ASCE 8–22, along with traditional effective width design approaches. The standard provides a robust set of provisions for slender austenitic, ferritic, and duplex cold-formed stainless steel structural members and their connections. This paper overviews major changes in the ASCE 8–22 standard highlighting areas of divergence from carbon cold-formed steel (AISI S100) and from stainless structural steel (AISC 370–21).
