Experiments on sheathed cold‐formed steel beam‐columns

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 were also undertaken. The tested specimens comprised a single 2.4 m long member sides secured at its ends top bottom tracks. Eight pure OSB connectors 75 mm 600 initially performed. Specimens then under combined loading, by first applying compressive load corresponding 75%, 50% or 25% predetermined axial resistance laterally loaded until failure. Reducing from resulted up 20% 30% increases capacity for studs respectively.
