2022 Code of Standard Practice for Steel Buildings and Bridges (ANSI/AISC 303)

The AISC Code of Standard Practice provides a framework for a common understanding of the acceptable standards when contracting for structural steel. As such, it is useful for everyone associated with construction in structural steel. Unless specific provisions to the contrary are contained in the contract documents, the existing trade practices that are contained therein are considered to be the standard custom and usage of the industry and are thereby incorporated into a contract between the related parties.
