Abstract

This paper summarizes results from an experimental program designed to evaluate the tension-compression cyclic axial response of cold-formed steel Csection structural framing members. A new cyclic loading protocol for coldformed steel members is presented that defines the target axial displacement based on elastic buckling parameters. The protocol is used to explore the cyclic response of members experiencing local buckling, distortional buckling, and global buckling deformation. In the experiments, post-bucking energy dissipation was observed along with tension stretching and softening. The quantity of dissipated energy per cycle increased as cross-section and global slenderness decreased. Specimens experiencing local and distortional buckling dissipated more energy per half-wavelength than those experiencing global buckling.
