Abstract

The global buckling behaviour of cold-formed steel complex angle sections subjected to axial compression is investigated. The length of the columns is considered to be 1 m upon preliminary analysis using CUFSM such that global buckling governs. Linear and non-linear finite element buckling analyses are carried out using commercial finite element software ABAQUS. Fixed boundary condition is assumed throughout the study. The column strengths and post-buckling capacities of the considered sections are presented. Influence of stiffener type on axial load capacity of the angle sections is discussed. The obtained numerical column strengths are compared with the Direct Strength Method (DSM) design strength equations of global buckling mode available in AISI-S100 and literature. On comparison, it is observed that the design equations in the available literature either underestimate or overpredict the capacity of complex-shaped angle members subjected to global buckling under axial compression.
