In 2016, AISI S100, North American Specification for the Design of Cold-Formed Steel Structural Members (or Specification), was updated with an entirely new layout which is parallel in format with ANSI/AISC 360, Specification for Structural Steel Buildings. Also, the Direct Strength Method has been integrated into the body of AISI S100, which enables engineers to design cold-formed steel members with unconventional cross-sections. …

In 2015 and early 2016, the American Iron and Steel Institute (AISI) published AISI S400-15/S1-16, North American Standard for Seismic Design of Cold-Formed Steel Structural Systems with Supplement 1. This first edition of AISI S400 represents a merging of the following previously published standards: …
Updated for 2018 IBC
From 2001 to 2012, the AISI Committee on Framing Standards developed nine different framing standards to cover specific aspects of cold-formed steel framing. Six of these standards addressed the design of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls. …
Municipalities have, or are in the process of adopting, the 2015 edition of the International Building Code (IBC). The 2015 IBC incorporates by reference AISI S100-12, North American Specification for the Design of Cold-Formed Steel Structural Members, 2012 Edition. To facilitate the use of AISI S100-12, the American Iron and Steel Institute (AISI) developed the 2013 edition of its Cold-Formed Steel Design Manual (Manual). …
American Iron and Steel Institute (AISI) cold-formed steel design and construction standards are developed and maintained by the AISI Committee on Specifications for the Design of Cold-Formed Steel Structural Members and the AISI Committee on Framing Standards. …
Most typical nonstructural partitions are specified and constructed in accordance with the industry or manufacturers’ design tables and would not require additional, formal engineering input on a project-by-project basis. The manufacturers’ design tables are based on engineering principles and tests. However, there are projects where the requirements are outside the limits of the manufacturers’ design tables. …
