In this paper, ductility capacity of composite beams is discussed. First, the results of cyclic loading tests with 4 full-scale composite beam specimens are shown. Each specimen was designed to have different joint efficiency at their beam-to-column connection. The tests results shows that the ductility capacity of the composite beam decreases as then- joint efficiency degrades. Especially, the ductility capacity of the specimens using RHS columns was poor. Experimental data of the neutral axis Next, the evaluation method of ductility capacity of composite beams is derived from experimental knowledge obtained here. Finally, the evaluation is verified with the experimental results. The evaluation follows the tendency of the experimental results, and this indicates that the proposed method is effective in examining ductility capacity of composite beams.
