Author Description

This edition of the Seismic Design Manual contains more than 2,040 pages of seismic design information for steel structures. It includes hundreds of pages of comprehensive design examples, including connections, updated for the 2022 AISC Seismic Provisions. Examples are shown with LRFD and ASD design methodologies side-by-side. 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 summarizes 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.
