Abstract
This paper describes the results obtained from experimental, numerical, and theoretical investigations into the load capacity of column members of lipped channel cross-section with perforations of different arrangements subjected to compression loading. Most structural cold-formed steel members are manufactured with pre-punched perforations to accommodate, for example, electrical, plumbing and heating services. Due to the position, orientation and the shape of perforations, the elastic stiffness and ultimate strength of a structural member can vary. The buckling behaviour of cold-formed steel structural column members with lipped channel cross-section, with perforations of different shapes were studied and comparisons of the finite element results and the test results are also made with existing design specifications and conclusions are drawn on the basis of the comparisons.
