Abstract
In order to verify the aseismic performances of mixed frame structures, tow story - two span frame type specimens were tested. In this paper, the effects of differences of beam-column joint details on the aseismic performances were discussed. From the experimental results, the effects of the differences of the beam-column joint details were investigated on the differences of story stiffness, ultimate strength and hysteresis loops. The aseismic performances of the joint details of the through beam type was less excellent than those of the through column type. For the verification of the test results, the frame analysis of the test specimens were carried. The analytical results for the stiffness, yield strength and hysteresis loops gave a good agreement with the experimental results.
