Building upon a previous set of experiments performed to determine connection rotational restraint provided by sheathing in cold-formed steel floor joists, this study investigates the reliability of reported connection ...

Laterally braced cold-formed steel beams generally fail due to local and/or distortional buckling in combination with yielding. For many cold-formed steel (CFS) studs, joists, purlins, or girts, distortional buckling may ...

A series of cantilever tests on joist-sheathing assemblies were conducted to determine the rotational restraint that sheathing provides to the compression flange of a floor joist in bending. This rotational restraint, which ...

Research on the distortional buckling of cold-formed steel columns, primarily C and Z shapes is summarized in this document.
