A large number of design equations of beam-to-column joint of hybrid structure composing of reinforced concrete columns and steel beams have been proposed so far. Most of these design equations are expressed by addtion of concrete strength and steel one in the joint. But, in practice, because the concrete in the joint is confined by the inner steel elements, the shear resistance mechanism is complex. In this paper, eight kinds of specimens using built-up square steel pipes in their joint were tested. In the experimental result, the larger the ratio of the breadth of the square steel pipe to the reinforced concrete column is. the smaller the width of the compression strut is and the less the shear resistance mechanism acts effectively. The larger the ratio of the height of the square steel pipe to the depth of the steel beam is, the higher the shear strength is, because of increase the confined effect to the joint. The shear resistance mechanism with the variation of the form of square steel pipes was evaluated definitely.
