The AISI Committee on Specifications for Cold-Formed Steel recently developed Supplement No. 1 to the 1996 Specification for the Design of Cold-Formed Steel Structural Members. The Supplement reflects new information developed through research projects, brings provisions in agreement with other specifications where appropriate, and also provides certain clarifications and corrections. The Supplement and the Specification have both been recently accepted as ANSI standards. The present paper reviews the major items included in the Supplement. The Committee continues to sponsor research projects aimed at developing a better understanding of particular areas of cold-formed steel behavior and more comprehensive design rules. Projects currently underway or recently completed are listed. As a result of a collaborative effort with representatives from Canada and Mexico, it is anticipated that the next edition of the specification will be referred to as the AISI North American Specification for the Design of Cold-Formed Steel Members
