Abstract


The Q420 dual-angle cross combined section columns with slenderness ratio from 25 to 55 under axial and eccentric compression were investigated by conducting experiments. The specimen parameters, experimental setup, and test results were presented. It showed that local buckling occurred apparently for specimens with slenderness ratio <35 under axial compression, while overall bending buckling appeared for others, and no torsional buckling occurred.
