Thin-walled perforated singly symmetric open-section columns and braces are commonly used in industrial storage rack structures. They are difficult to analyze accurately because the shear center and centroid do not coincide and the complex buckling modes are involved. This paper explores the application of the newly extended MASTAN2-v5 program to analyze rack frames, using the advanced line-finite element formulations that capture the global buckling modes. Modeling of perforations on the columns is explored, and the refined buckling strength equations are proposed for considering local and distortional buckling. Finally, validation examples and case studies for multistory pallet racks are given.
