FOR IMMEDIATE RELEASE

CHICAGO - The American Institute of Steel Construction has updated the industry’s go-to reference for all things seismic design.

The fourth edition AISC Seismic Design Manual expands upon the guidance in the third edition and incorporates the 2022 AISC Seismic Provisions for Structural Steel Buildings, the 2022 AISC Specification for Structural Buildings, and recent design guides.

It’s now available in both digital and print formats.

“Researchers and earthquake engineering experts continuously develop new ways to keep us safe during seismic events,” said AISC Vice President of Engineering and Research Chris Raebel, SE, PE, PhD. “This updated Manual brings all of the latest information together into one volume designed to help engineers design safe, efficient structures more quickly and easily.”

This revision adds design examples for multi-tiered buckling-restrained braced frames, concentrically braced frame column bases, and connection design at the intersection of braces in a concentrically braced frame. Another updated example considers partial-joint-penetration groove welds for a column splice in a special moment frame.

New tables summarize applicable requirements of the AISC Seismic Provisions as well as second-order amplifier values for use with approximate second-order analysis. An updated discussion of diaphragms considers load path, challenges in analysis, and common assumptions, along with guidance on diaphragm modeling.

The new Seismic Manual is available at aisc.org/publications.
