The authors have investigated a mixed structure composed of reinforced concrete columns and steel beams. In this paper, two types of beam-column joints, through beam type and through column type, are proposed. In order to clarify the behavior of these joints under the earthquake loading, experimental tests were carried out by using eighteen specimens of beam-column model assemblages. The design procedures are proposed through the study on the shear strength, deformation and bar bond strength in the joint based on the test results.
