ANSI/AISC 341-22 Seismic Provisions for Structural Steel Buildings

The information presented in this publication has been prepared by a balanced committee following American National Standards Institute (ANSI) consensus procedures and recognized principles of design and construction.

The Specification for Structural Steel Buildings (ANSI/AISC 360-22) is intended to cover common design criteria. This standard, Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-22) (hereafter referred to as these Provisions), is a separate consensus standard, to be used in conjunction with the Specification, that addresses the design and construction of structural steel and composite steel-concrete building systems specifically detailed for seismic resistance. This standard adopts Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358-22) by reference. ANSI/AISC 358 specifies design, detailing, fabrication, and quality criteria for connections that are prequalified in accordance with these Provisions for use with special and intermediate moment frames. While these Provisions are modified every five or six years, ANSI/AISC 358 may be processed more frequently, and newer editions of ANSI/AISC 358 may be recognized and enforced by the applicable building code. These Provisions were being developed in the same time frame as a revision of Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE/SEI 7-22). ASCE/SEI 7-22 is to be used concurrently with this standard for a fully coordinated package. These Provisions are the result of the consensus deliberations of a committee of structural engineers with wide experience and high professional standing, representing a wide geographical distribution throughout the United States. The committee includes approximately equal numbers of engineers in private practice and code agencies, engineers involved in research and teaching, and engineers employed by steel fabricating and producing companies. The contributions and assistance of more than 50 additional professional volunteers working in task committees are also hereby acknowledged.
