Aisc 325 Steel Construction Manual Upd Jun 2026

When designing a shear end-plate connection, the failure mode is often web crippling or web local yielding at the toe of the fillet (distance "k"). The k dimensions are in Part 1, but 90% of engineers forget to check them.

In Part 16, the Specification is followed by a comprehensive "Commentary" section. If an equation or structural limit state seems confusing, the commentary explains the academic research, testing history, and intent behind the rule.

These sections provide strength tables for flexural members (beams), compression members (columns), tension members, and members subject to combined forces. aisc 325 steel construction manual

If you haven’t already, order a current copy (either the 15th or 16th edition) today. Spend an hour flipping through the Parts. Locate Table 3-2, Table 4-1, and the bolt tables in Part 7. You will quickly realize why generations of engineers call it simply, “The Manual.”

AISC 325 and the 16th Edition manual are available for purchase directly from the AISC website or through various standards distributors.

The manual is structured into that provide comprehensive design aids, material specifications, and regulatory standards. It integrates critical industry codes, such as the ANSI/AISC 360: Specification for Structural Steel Buildings and the ANSI/AISC 303: Code of Standard Practice.
