A 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 aisc.org/standards.
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.
The document is free to download; a printed version will be available for purchase from aisc.org/publications this summer.
