AISI Publishes New Standard for Nonstructural Members

WASHINGTON, D.C., January 26, 2012 – The American Iron and Steel Institute (AISI) has published a new standard for nonstructural members. AISI S220, North American Standard for Cold-Formed Steel Framing – Nonstructural Members, 2011 Edition and Commentary are available for downloading free of charge (click here).

Developed by AISI’s Committee on Framing Standards, AISI S220 is applicable to commonly recognized nonstructural members such as wall studs used in interior partition walls. It is also applicable to other members, as long as they meet the nonstructural definition and limitations.

“This new publication brings the design and manufacturing requirements for cold-formed steel nonstructural members into one standard, making it easier for design professionals to specify and building officials to approve steel for building projects,” Jay Larson, P.E., F. ASCE, Managing Director, Construction Technical Program, said. “The standard is exceptional in that it was developed by a consensus committee, subjected to an independent public review process, and then was approved by the American National Standards Institute (ANSI) in less than six months, allowing us to transfer this information to the design community in a tightly compressed timeframe.”

AISI’s codes and standards work is conducted under the Construction Market Council of the Steel Market Development Institute (SMDI), a business unit of AISI, which oversees the industry’s investment in advancing the competitive use of steel by meeting the demands of the marketplace.
