In order to study the hysteretic behavior and restoring force model of cold-formed thin-walled steel (CFTWS) lipped channel beam-column, a finite element analysis (FEA) considering material geometric nonlinearity influence initial imperfection under cyclic loading was established by ABAQUS software. Based on verified FEA model, CFTWS beam-column members with different influencing factors analyz...

An experimental study on sheathed cold-formed steel C-lipped columns (studs) with service holes in the web subjected to compression and major axis bending is presented this paper. A total of 17 experiments was performed both oriented strand board (OSB) plasterboard used as sheathing material varying connector spacing employed between members. Material tests geometric imperfection measurements w...
