Abstract
In cold-formed stainless steel lipped channel-sections, use of web openings for service purposes are becoming increasingly popular. Web openings, however, result in the sections becoming more susceptible to web crippling. This paper presents a finite element investigation into the web crippling strength of cold-formed austenitic stainless steel lipped channel-sections with circular web openings under the interior-two-flange (ITF) loading condition. The cases of web openings located centred and offset to the bearing plates are considered in this study. In order to take into account the influence of the circular web openings, a parametric study involving 740 non-linear elasto-plastic finite element analyses was performed, covering austenitic EN1.4404 stainless steel grade. From the results of the parametric study, the effect of the size of the web opening, length of bearing plate and location of the web opening is investigated. Strength reduction factor equations are then proposed, that can be used to take into account such web openings in design.
