AISI Design Standards Adopted In 2024 Edition I-Codes
This Standard applies to the design of structural members cold-formed to shape from carbon or low-alloy steel sheet, strip, plate, or bar not more than 1 in. (25.4 mm) in thickness and used for load-carrying purposes in buildings, and structures other than buildings provided allowances are made for dynamic effects.
