AISI Updates Six Cold-Formed Steel Design Standards

January 5, 2021

WASHINGTON, D.C. – The American Iron and Steel Institute (AISI) has updated six cold-formed steel design standards. AISI is an accredited consensus organization by the American National Standards Institute (ANSI) for developing American National Standards (ANS). The task of creating and updating cold-formed steel design standards is accomplished through two voluntary consensus committees—the AISI Committee on Specifications and the AISI Committee on Framing Standards. The standards are available for free download at https://www.cfsei.org/free-aisi-standards.   

The updated standards include:

  • AISI S202, Code of Standard Practice for Cold-Formed Steel Structural Framing
  • AISI S220, North American Standard for Cold-Formed Steel Nonstructural Framing
  • AISI S240, North American Standard for Cold-Formed Steel Structural Framing
  • AISI S310, North American Standard for the Design of Profiled Steel Diaphragm Panels
  • AISI S400, North American Standard for Seismic Design of Cold-Formed Steel Structural Systems
  • AISI S100-16 (2020) w/S2-20, North American Specification for the Design of Cold-Formed Steel Structural Members, 2016 Edition (reaffirmed 2020) with Supplement 2 

“These updated standards have been approved by ANSI and adopted into the 2021 International Building Code,” said Jay Larson, P.E., F.ASCE, managing director of AISI’s Construction Technical Program. “They include the most up-to-date industry research and state-of-the-art practices and reflect significant changes that ensure steel’s reliability and competitiveness with other materials in the construction market. We appreciate the work of all the researchers who helped expand the body of knowledge and the diligence of the members of the AISI Committee on Specifications and the AISI Committee on Framing Standards in considering proposed changes, reviewing comments, and refining the provisions of these important standards.”

AISI serves as the voice of the American steel industry in the public policy arena and advances the case for steel in the marketplace as the preferred material of choice. AISI also plays a lead role in the development and application of new steels and steelmaking technology. AISI’s membership is comprised of integrated and electric arc furnace steelmakers, and associate members who are suppliers to or customers of the steel industry.
