AISC

The American Institute of Steel Construction (AISC) is a nonprofit trade association based in the United States that serves the structural steel design and construction industry. It represents steel producers, fabricators, and erectors, and works to advance the use of structural steel through updated design standards, technical guidance, and certification programs.

AISC develops and maintains design standards and specifications for structural steel, and publishes reference manuals such as the Steel Construction Manual. The most widely used standards include the AISC 360 Specification for Structural Steel Buildings and the AISC 341 Seismic Provisions, which are incorporated into engineering practice and many building codes. AISC also produces design aids, software interfaces, technical bulletins, and other resources to support engineers, fabricators, and contractors.

AISC operates certification programs for fabricators and erectors to verify capability and quality control. The AISC Certification Program assesses quality management systems, welding procedures, inspection and testing, and production processes to ensure consistent performance in fabrication and construction. The institute also provides education resources, continuing education opportunities, and market research to support its members and the broader industry.

History and scope: AISC was founded in 1921 by steel producers and users to promote safe, economical steel construction. Over time it expanded to a national organization with regional chapters and an influential role in developing and maintaining standards used widely in the U.S. for commercial, institutional, and industrial steel structures.
