Full Name

ICC-ES AC322 – Acceptance Criteria for Prefabricated, Cold-formed Steel, Lateral-force-resisting Vertical Assemblies

Scope

ICC-ES AC322 establishes the acceptance criteria for prefabricated, cold-formed steel, lateral-force-resisting vertical assemblies. These assemblies are intended for use in buildings to resist lateral loads from wind and seismic events.

The scope of AC322 includes:

  • Materials: it specifies the acceptable types of cold-formed steel materials, fasteners, and connectors that can be used in the assemblies.
  • Design and construction: it outlines the design and construction requirements for the assemblies, including the configuration of the framing members, bracing elements, and connections.
  • Performance: it defines the performance criteria that the assemblies must meet, such as the lateral load capacity, stiffness, and deflection limits under wind and seismic loads.
  • Testing: it details the testing procedures and protocols for evaluating the performance of the assemblies, including static and cyclic lateral load tests.

By defining these criteria, AC322 ensures that prefabricated, cold-formed steel, lateral-force-resisting vertical assemblies meet the necessary standards for safety and performance in resisting wind and seismic loads. This provides confidence to building officials, designers, and builders that these assemblies are suitable for use in building construction.
