Standards Committees

AISI is an accredited consensus organization by the American National Standards Institute (ANSI) for developing American National Standards (ANS). The AISI Committee on Specifications and the Committee on Framing Standards are the consensus committees that follow the American Iron and Steel Institute Procedures for ANSI-Approved Standards for Cold-Formed Steel Design and Construction. The committees welcome any interested groups to participate in their activities. For further information, please contact Helen Chen.

Committee on Specifications

The AISI Committee on Specifications for the Design of Cold-Formed Steel Structural Members is a consensus group which maintains and updates the North American Specification for the Design of Cold-Formed Steel Structural Members (AISI S100), North American Standard for the Design of Profiled Steel Diaphragm Panels (AISI S310), and a series of cold-formed steel test standards (AISI S900 series). AISI S100 is the foundation for many construction products including steel decking, steel roofing and wall panel systems, metal building systems, storage racks and cold-formed steel framing. The Specification is recognized by American National Standards Institute (ANSI) as the American National Standard in the United States, by CSA Group in Canada, and by Camara Nacional de la Industria del Hierro y del Acero (CANACERO) in Mexico. The test standards have also been approved by ANSI as the American National Standards.

Mission

To improve the performance of cold-formed steel in structures through the development and use of improved analysis methods and design specifications.

The Committee on Specifications consists of eight subcommittees. These subcommittees fulfill the mission established by the Committee on Specifications by monitoring research works related to cold-formed steel design and by providing recommendations for developing and improving design provisions in assigned AISI standards (see above).

The Committee on Specifications is structured as follows:

Committee on Framing Standards

The Committee on Framing Standards is an ANSI-accredited consensus body which maintains and updates the suite of AISI framing standards:

• AISI S202 – Code of Standard Practice for Cold-Formed Steel Structural Framing
• AISI S220 – North American Standard for Cold-Formed Steel Framing — Nonstructural Members
• AISI S230 – Standard for Cold-Formed Steel Framing — Prescriptive Method for One and Two Family Dwellings
• AISI S240 – North American Standard for Cold-Formed Steel Structural Framing
• AISI S250 – North American Standard for Thermal Transmittance of Building Envelopes With Cold-Formed Steel Framing
• AISI S400 – North American Standard for Seismic Design of Cold-Formed Steel Structural Systems

These standards reference AISI S100, North American Specification for the Design of Cold-Formed Steel Structural Members, which is the foundation for cold-formed steel design.

Mission

To improve the performance of cold-formed steel framing in building construction through the development and use of improved design and installation standards.

The Committee on Framing Standards consists of four subcommittees. These subcommittees fulfill the mission established by the Committee on Framing Standards by monitoring research works related to cold-formed steel framing design, and providing recommendations for developing and improving design provisions in the cold-formed steel framing standards.

The Committee on Framing Standards is structured as follows:

Committee on Energy Standards

The Committee on Energy Standards is an ANSI-accredited consensus body which maintains and updates the following AISI energy standard:

• AISI S250 – North American Standard for Thermal Transmittance of Building Envelopes with Cold-Formed Steel Framing

Mission

To develop and maintain methods for determining heat transfer through building envelopes for assemblies containing cold-formed steel and other materials; develop prescriptive and performance solutions for code compliance, construction details, and installation quality standards; and address other similar issues that impact cold-formed steel in the energy codes and standards arena.

The Committee on Energy Standards is structured as follows:
