The objects of this study are to give consideration to the mechanical behavior of beam-column subassemblage with different floor levels on both sides of column, and also to estimate the shear strength of joint in such a subassemblage. The parameters of test series are the method of beam bar anchorage within a joint, the distance between one beam axis and the other beam axis on both sides of column, and loading directions. The influence of these parameters on the ultimate strength of joint is estimated from test results. In the specimen which the distance between one beam axis and the other beam axis is smaller than a beam depth, the horizontal joint shear force at joint shear failure is larger than the joint shear strength of interior joint type as the distance increase. In the specimen which the distance is equal to a beam depth, the ultimate joint shear force can be estimated by the shear strength of exterior joint type.
