Steel institute’s new report focuses on clip angle design

The American Iron and Steel Institute (AISI) has published a new cold-formed steel research report on loadbearing clip angle design. The report “RP18-4: Load Bearing Clip Angle Design – Phase II” presents the second phase of a research project aimed at developing design methods for three limit states of cold-formed steel clip angles—shear, compression, and pullover of the screw connections.
