Abstract
This paper describes a numerical investigation into distortional-global buckling interaction of cold-formed steel perforated rack uprights when subject to axial compression. The numerical modelling strategy is carefully validated against existing experimental data. The strengths and failure modes of perforated uprights obtained from finite element analysis are compared with design strengths predicted using the direct strength method (DSM). The comparisons indicate that the ultimate strengths predicted by the current DSM are unsafe for perforated rack uprights. Hence, modifications on the DSM formulae were proposed and are presented by considering the interaction of distortional and global buckling modes for perforated rack uprights.
