Hybrid structures (RCS) consisting of reinforced concrete columns and steel beams have been developed in Japan. Many studies have been conducted on the behavior of cross-shaped beam-column joints; however, there have been few experimental and analytical studies on the behavior of RCS frames. In this research, a nonlinear three-dimensional finite element analysis of an RCS frame specimen with through-beam type beam-column joints has been conducted. From the analytical results, the following conclusions were obtained. (1) The analytical results showed good agreement with the experimental results for the load-deformation relationships. (2) A compressive strut was formed from the outer concrete to the inner concrete in the joint area divided by transverse beams. (3) The torsional deformation component between the outer panel and the inner panel occupied a large rate in the panel deformation of the beam-column joints. (4) The ratio of the components which were assumed in the proposed equations of the shear capacity for the cross-shaped beam-column joints were different from the ratio which was obtained from the analytical results.
