The proposed model consists of two curves, one of which is intended to depict the ascending branch and account for the effect of residual stress induced during the manufacturing process, and the other is to depict the descending portion and account for the effect of local buckling, either elastic or inelastic. Test results of thirtyfive circular steel stub columns under monotonic axial compression are collected to calibrate and validate the model. The experiments were conducted in Japan and Australia. The previous tests of circular stub columns under concentric compression cover a wide range of structural factors such as D/t ratio and yield strength of steel tube. The D/t ratio ranged from 16.7 to 221, while the yield strength varied from 186 MPa to 835 MPa. Comparisons between the experimental stressstrain curves and theoretical results indicated that the proposed model could simulate compressive stress-strain behavior of CHSS columns up to large strain with very high accuracy.
