Abstract: Tests were conducted on six L-shaped concrete-filled steel stub columns (CFSSC) and one L-shaped steel hollow column. The nonlinear damage process and the failure mode of the specimens were described. The influences of structural parameters on the axial bearing capacity of L-shaped CFSSCs were investigated. These structural parameters included the width-to-thickness ratio of the steel plate, with or without stiffeners, and the limb length. The experimental results indicated that the confined effect of the steel tube on the infilled concrete was more distinct for an L-shaped CFSSC with a short limb than one with a long limb. For an L-shaped CFSSC with a short limb, the stiffeners may improve the ductility of the specimens to the extent of 1.5 times although they were less effective in improving the bearing capacity. On the other hand, the stiffeners were ineffective in both improving bearing capacity and ductility of the L-shaped CFSSC with a long limb.
