This paper presents a study on cross-section stability of stainless steel circular hollow sections by using the finite element analysis method. A numerical parametric study was performed which covered the finite element analysis of models of stainless steel circular hollow section members. The study was carried out over a practical range of cross-sections slenderness values. An experimentally validated finite element program (ABAQUS) was used to model the range of members under pure bending. For all the models non-linear load-deflection response curves were obtained and maximum moments were calculated. The finite element predictions for moment strength were compared with the estimations of the currently available structural stainless steel codes. The study has provided evidence supporting the use of higher D/t (diameter/thickness) ratio limits to permit use of simple elastic and plastic moment for the calculation of the bending moment capacity of stainless steel tubular beams.
