N2 - In recent years, the progressive collapse of buildings increases the interest in progressive collapse studies. If a key column fails in structure, the internal force is redistributed by the catenary action of joint to prevent its progressive collapse. The joint connecting to the failed column is under the state of bending moment combined with tensional force and the tensional force would affect the moment-resistance ability and ductility of joint. In this paper, the finite element software ABAQUS is applied to analyze the behavior of composite joints under the state of bending moment combined with tensional force. The effects of rebar ratio, rebar strength, concrete strength, etc., on the behavior of joints are investigated. The results show that high strength steel is suggested to be used in composite joint to improve its bending moment capacity and tensional capacity.
