Updated Seismic Standard for Cold-Formed Steel
Posted by Alison Trost on May 25, 2010 at 9:50 AM.

The American Iron and Steel Institute (AISI) has published an update to its S110-07-S1-09, Standard for Seismic Design of Cold-Formed Steel Structural Systems—Special Bolted Moment Frames With Supplement No. 1. The standard addresses the design and construction of cold-formed steel seismic force-resisting systems (SFRS) in buildings and other structures, with focus on the special bolted moment frame (CFS-SBMF) system.

Cold-formed steel special bolted moment frames have been widely used in industrial platforms, and the system is potentially suitable for a broad range of construction applications. Revisions and additions were made in Supplement No. 1 to ensure that the application of the design provisions remains within the configurations used in the initial research of special bolted moment frames. The commentary on the standard is also included, which provides important background information. This standard should be used in conjunction with AISI S100-07, The North American Specification for the Design of Cold-Formed Steel Structural Members. All of these publications are available for purchase online at AISI’s Publications Bookstore at
