AISI Publishes Supplement No. 1 to AISI S905-08, Test Methods for Mechanically Fastened Cold-Formed Steel Connections

WASHINGTON, D.C., April 24, 2012 – The American Iron and Steel Institute (AISI) has published Supplement No. 1 to AISI S905, Test Methods for Mechanically Fastened Cold-Formed Steel Connections, 2008 Edition. The Supplement was issued to address questions raised by the International Code Council Evaluation Service, Inc. (ICC-ES). AISI S905-08, Test Methods for Mechanically Fastened Cold-Formed Steel Connections, 2008 Edition and Supplement No. 1 is available for sale as an electronic publication on AISI’s online store (click here). 

“The performance test methods in AISI S905 cover determination of the strength and deformation of mechanically fastened connections for cold-formed steel building components. In Supplement No. 1, a test setup was added to cover the geometric condition of an application with a small edge dimension, allowing the test method to be used for these special cases,” Jay Larson, P.E., F. ASCE, Managing Director, Construction Technical Program, said. Larson commented that this information would impact the work of code regulators and officials, code influencers, specifiers, designers, researchers, and steel industry customer associations.

AISI S905-08 and Supplement No. 1 were developed by AISI’s Committee on Specifications for the Design of Cold-Formed Steel Structural Members. AISI S905-08 and Supplement No. 1 have been approved as American National Standards by the American National Standards Institute (ANSI). A new edition of the Standard is being formulated and is targeted for completion in either late 2012 or 2013. 

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.
