American Institute of Steel Construction

U.S. domestic-industry trade association

Background

AISC traces its origins to 1911, when the Bridge Builders Society and the Structural Steel Society began jointly developing codes of practice; the two groups merged into a War Service Committee during World War I and formally incorporated as AISC in 1921–1922. For over a century the organization has served as the authoritative source for structural steel design standards in the United States, publishing the Steel Construction Manual (first issued 1927, now in its 16th edition) and the peer-reviewed Engineering Journal. It also publishes Modern Steel Construction, the only U.S. monthly magazine dedicated exclusively to structural steel design and fabrication. AISC develops its technical standards through consensus bodies accredited by the American National Standards Institute (ANSI), giving them quasi-regulatory weight in building codes. On the policy side, AISC has long lobbied for Buy America provisions and domestic-production protections; it applauded the Trump first-term Section 232 tariffs on imported steel and, in the second term, publicly supported the February 2025 presidential action that added fabricated structural steel as a protected downstream derivative product. The organization has not been the subject of major editorial or financial controversies, though its advocacy record makes clear it functions as a voice for domestic producers rather than a neutral technical body.
