This report presents a comprehensive parametric study on the ultimate strength of perforated cold-formed steel columns using the Finite Element package ABAQUS. FE models were first developed for columns predisposed to local, distortional and global buckling failures respectively. Modelling issues such as boundary conditions, meshing, initial imperfections, material models amd non-linear solution controls in FEA were addressed. The parametric study involved 5 cross-section types i.e. C, stiffened C, Z, rack amd hat sections.
