Second Edition AISC Design Guide for Hollow Structural Section Connections Now Available

Design professionals now have a vastly improved resource for the design of hollow structural section (HSS) connections in the new second edition of AISC Design Guide 24, Hollow Structural Section Connections, authored by Jeffrey Packer, PEng, PhD, DSc, professor in the University of Toronto’s Department of Civil and Mineral Engineering, and Kimberley Olson, PE, director of Nucor’s Construction Solutions Group.

Design Guide 24, 2nd Ed. is available for download at Like all digital design guides, it is free for AISC members.

This latest update to the AISC design guide series greatly expands upon the background and commentary for each HSS connection. These thorough explanations of the relevant limit states and the experimental results for each connection provide invaluable insight into the rationale behind each connection design procedure.

The design guide has been expanded to include guidance and design procedures for many new connection types, and a dozen new design examples bring the total to 33! This new edition has also brought the discussions, guidance, and procedures for HSS connection design into conformance with the provisions of the current Specification for Structural Steel Buildings (ANSI/AISC 360-22) as well as the new 16th-ed. Steel Construction Manual.

The second edition includes extensive background for each of the various limit states relevant to HSS connections, including welded joints and mechanically fastened/bolted joints. It also discusses design procedures for numerous shear connections, moment connections, tension/compression connections, line load/concentrated force connections, HSS-to-HSS truss connections, and HSS-to-HSS moment connections.
