Cold-formed steel sections have become competitive structural components in the modern building construction due to their inherent favourable characteristics over conventional hot-rolled steel members. A wide range of products, with a multiplicity of shapes, sizes, and applications typically manufactured with perforations to facilitate various services: electrical, plumbing, and heating, etc., are produced using simple and cost-effective industrialised processes. Cold-formed members are thin, light, and economically efficient. However, the advantages of these members are often limited due to the presence of perforations and susceptible to various buckling modes such as local, distortional, flexural, and torsional-flexural buckling which sometimes are not predicted. This research work provides a general insight into cold-formed steel and buckling, and investigates the influence of perforations on the buckling behaviour of cold-formed column members of lipped channel cross-section using experimental study, finite element analysis, and design code predictions.
