AISC Releases New Seismic Standard for Existing Steel Buildings



A brand new standard, Seismic Provisions for Evaluation and Retrofit of Existing Structural Steel Buildings (ANSI/AISC 342-22), is now available as a free download from

The AISC Committee on Specifications developed and approved the document as a revision to the structural steel provisions in the 2017 edition of ASCE/SEI 41, Seismic Evaluation and Retrofit of Existing Buildings. The next release of that standard will likely adopt ANSI/AISC 342-22 in chapter 9.

"ANSI/AISC 342-22 provides vital updates to the existing provisions," said James Malley, chair of the AISC Committee on Specifications and a senior principal at Degenkolb Engineers. "ASCE/SEI 41 is a crucial standard for public safety and therefore it's absolutely critical that it reflects the latest structural steel research and understanding. I'd like to thank the members of the Committee for devoting their expertise to develop ANSI/AISC 342-22 over the course of the last seven years."
