In order to simplify a beam-column joints for concrete costing, and constructions in a mixed structure, the details of joints with reinforced concrete clumns and steel beams were developed in authors' previous experimental study. In order to investigate the shear resisting mechanism of the joints, it is necessary to cosider internal stress transfer mechanisms based on the analytical study. In this study, 3-D non-linear finite element analysis was performed to investigate the shear behavior of the joints. The analytical results gave good agreements with the test results. The effective area of concrete and steel in the joint was evaluated by observation of analytical principal stress distributions. From the analysis, it was found that the shear strength of the joints was influenced by the section details of beams and columns. Finally, the shear strength of the joint were investigated by carrying out the numerical tests.
