Engineers refer to Part 5 when designing bracing, hangers, and trusses. It covers net area calculations, shear lag factors, and block shear rupture. Part 6: Design of Members Subjected to Combined Forces

This is often considered the most practical section for designers.

: The 16th Edition includes expanded discussions and tables for prying action and wrap-around gusset plates, which are traditionally some of the more tedious connection calculations. Core Manual Structure

standards in action. For structural engineers and architects, the AISC 325 Steel Construction Manual

AISC also provides errata and corrections for each edition of the manual. For the 16th Edition, separate errata lists are provided for the Specification and Code. For the 15th Edition, the manual errata includes the corresponding errata for the Specification. These resources are essential for maintaining the accuracy of your manual.

This section parallels Chapter E of the spec. Key tools include:
