The American Iron and Steel Institute (AISI) has published a new test standard in its S900-series—AISI S919-17, Test Standard for Determining the Flexural Strength and Stiffness of Cold-Formed Steel Nonstructural Members. The test standard has been approved by the American National Standards Institute (ANSI) as the American National Standard and is available for downloading free of charge at www.aisistandards.org.
“This test standard was developed by AISI’s Committee on Specifications and is intended for adoption and use when performance testing of the cold-formed steel nonstructural member is required,” said Jay Larson, P.E., F.ASCE, Managing Director, Construction Technical Program. “It can be used to determine the nominal flexural strength (resistance) for both local buckling and distortional buckling failure modes. The test standard provides an alternative approach to evaluating the flexural strength and stiffness of nonstructural members.” Larson noted that AISI S919-17 completes AISI’s suite of 2017 Edition standards. Each standard is available for free download atwww.aisistandards.org.
AISI test standards are updated every five years and facilitate research and development leading to improved state-of-the-art solutions in steel for the construction market. They are often referenced in industry acceptance criteria, and lead the way in establishing the performance characteristics of unique products and applications.
