What it governs

The specification for structural steel buildings in the United States — how a steel member or connection is proportioned for strength, stability and serviceability. It covers the design of the member and the joint.

Fabrication tolerances, welding procedure and bolt manufacture sit in separate documents it references, and the steel's own chemistry sits in an ASTM material standard. Both design philosophies live in one book: load and resistance factor design, and allowable strength design.

A calculation is only comparable with another when both used the same one. Stability is its subtlest subject.

A member adequate in isolation can be inadequate in a frame, because the frame's own sway changes the demand on it — which is why a column check that ignores the analysis method behind it is incomplete. Serviceability is deliberately left to the engineer: it gives no deflection limit, and the limits used in practice come from the building code, the cladding manufacturer, or judgement about what the finishes will tolerate.

Editions

This site holds no edition list for AISC 360, so a citation here names AISC 360 rather than a year. The publisher above has the current designation.

Adoption is not verified for your jurisdiction. A model document binds only where an authority adopted it, usually some editions behind and amended locally. Citing a clause is not conformance. No part of the text is reproduced here.
