The History of the Development of the Single Angle Design Provisions in the AISC Specification

There was very limited guidance on the design of single-angle members in 1978 in the AISC specification (AISC, 1978). Pressure for more guidance from industry and the government led to AISC forming a task committee to develop design provisions for single angles. This led to development of a separate specification dedicated to the design of single-angle members. The initial specification was an Allowable Stress Design version. This was followed by LRFD versions. Ultimately it was decided to assimilate single angle provisions into the main specification along with the provisions for hollow structural shapes.
