The American Institute of Steel Construction (AISC), a not-for-profit structural steel technical institute, partners with the AEC community to develop safe and efficient steel specifications and codes while driving innovation to make steel the most sustainable, economic, and resilient structural material on the market.

AISC offers an extensive collection of documents and publications related to the design and construction of fabricated steel buildings and bridges. Many of our documents are free downloads to the general public, and thousands more are free downloads for AISC members.

AISC's research programs are well known and highly respected for advancing the state of the art of steel design and construction. Our research activities help improve steel codes and specifications, reduce the cost of steel construction, and improve the performance of steel buildings and bridges.
