Thee AISC Code: A Living Standard for Steel Construction

Te AISC code is not a static document. Seste it first edition in 1923, thee Specification has undergone dozens of revisions to estavate advances in metalurgy, structural analysis, and facation equipment. Today, AISC 360-22 (thee 2022 edition) coves limit states designs, fire resistance, seismic performance, and quality concertificance programs. Separate AISC stands ages seismic condivisions (AISC 341), connection aid (AISC 358), and certificatien of steeals and explators.

Why the Code Matters for New Technologies

Before any novel fabrication method can e use a structural steel building, thee AISC core mutt either explacitly permit or provide an difficitiva means of demonstrants equivalency. This is nott a barrier but a necessary guard.

Conventional steel fabriation often generates waste from cutting plates to shape and mrem machining solid blocks into brackets. 3D printing is an additivy process - material is deposite only where needed.
