A series of tests were performed to evaluate the cyclic behaviors of box-section steel beam-columns under cyclic bending. The test was set up as a cantilever beam-column, loaded with cyclic transverse shear force at its free end, while the axial compression kept unchanged. Three sets of tests with various axial compression ratios were tested to find out their influencing on cyclic behaviors, which were 0.0, 0.4 and 0.6, respectively. In each set, there were five members with various width-to-thickness ratios of plates to consider their effects. The hystereticcurves and failure mechanisms of each member were given according the test results, and the main influencing factors, such as axial compression ratio of the member, width-to-thickness ratio of its plates, were analyzed. Then, the test results were compared with that of numerical analysis by the author. In general, there was a good agreement between two results, it revealed that the numerical analysis was reasonable and could be used in practice.
