Abstract:
Cold-formed sections are widely employed in steel construction because they are lighter and more economical than traditional hot-rolled members. CFS sections are recently been utilized in construction due to their numerous advantages such as higher load-to-weight ratio, flexibility to shape as well as availability in relatively long spans. CFS channel sections can be used as purlins and joists in the structural system; thus, they are vulnerable to different buckling instabilities including web crippling. Validation of cold-formed steel lipped channel sections with web openings subjected to web crippling was undertaken using finite element (FE) analysis, to investigate the effects of web holes and cross-section sizes on the web crippling strengths of channel sections subjected to web crippling under end-two-flange (ETF) loading conditions. In this loading conditions, the hole was placed at a horizontal distance(offset) to the nearing edge of the bearing plate. It was demonstrated that the main factors influencing the web crippling strength are the ratio of the hole depth & thickness of the web. Web openings could be used in cold-formed steel beam members, such as wall studs or floor joints, to facilitate ease of services in buildings. In this paper a combination of tests using finite element analyses method is used to investigate the effect of such holes on web crippling under end-one-flange (ETF) loading condition. The present paper includes web crippling strength of channel section by numerical study, where the models are validated against the performed experiments.
