This paper presents a non-linear finite element procedure for the strength determination of cold-formed box columns. The effects of residual stresses, local buckling, and initial imperfections, are all included in the analysis. The proposed theory is validated and its accuracy assessed against experiments conducted at the University of Sydney. A table for the strength of the sections with various member slenderness (L/r) and plate element slenderness (b/t) ratios is also produced, so that the typical relationship between the strength and these two ratios can be understood. The suggested method can be utilised to supplement experiments in the generation of design curves and in the parametric studies of the behaviour of cold-formed hollow sections subjected to various types of loading and boundary conditions.
