き、建物の安全性を確保することができる。EFFECT OF THE INVENTION In a joint structure of a reinforced concrete column and steel beams in which steel beams are integrally formed so as to intersect with each other, and the intersecting portions are arranged and joined in the reinforced concrete columns, the bearing reinforcing plate is used as the reinforced concrete column. Since the outer circumferential surface of the steel beam is located on both sides of the upper and lower flanges of the steel beam, it will spread the bearing force to the concrete at the joint even if the steel beam is bent by external force such as seismic force. Therefore, it is possible to suppress the occurrence of compressive failure due to bearing pressure, improve the deformation performance of the joint frame, and ensure the safety of the building.
