Abstract

Upper-bound estimation of the load-capacity of cold-formed steel sections (TWCFS) with perforations, subjected to axial compression is presented. The estimation is performed on the basis of the Yield Line Analysis ((YLA). TWCFS lipped channel sections with two sets of perforations (on the web and on the flanges) are under investigation. The comparison of experimental results, FE simulation results, European code ultimate strength predictions and upper-bound estimation based on YLA approach is carried out and presented. Some conclusions concerning an applicability of the YLA approach for ultimate strength prediction of perforated
TWCFS structural members are derived.
