Connection joint of steel reinforced concrete beam and concrete filled steel tubular column
The invention relates to a connection joint of a steel reinforced concrete beam and a concrete filled steel tubular column. The connection joint between the steel reinforced concrete beam and the concrete filled steel tubular column includes a steel tubular column, a cross beam and at least one pair of steel beam connector; two steel beam connectors of the same pair are located on both sides of the steel tubular column; an upper longitudinal bar and a lower longitudinal bar are arranged on each pair of steel beam connectors, and the upper longitudinal bars and the lower longitudinal bars are arranged along the corresponding steel beam connector and span the steel tubular column; stirrups are arranged on the outer part of the upper longitudinal bar and the upper part of the lower longitudinal bar of the same pair of steel beam connectors in a surrounding mode correspondingly, and the upper longitudinal bars, the lower longitudinal bars and the stirrups form a steel reinforcement cage. The upper longitudinal bars, the lower longitudinal bars and the stirrups form the steel reinforcement cage, the upper longitudinal bars and the lower longitudinal bars simultaneously correspond to thesteel beam connectors on the opposite two sides of the steel tubular column, that is, the steel reinforcement cage simultaneously correspond to the steel beam connectors on the opposite two sides ofthe steel tubular column. A part of the bending moment is transmitted to the opposite side through the steel reinforcement cage, the stress concentration of the steel beam and the steel tubular columnis reduced, and the stress of the connection joint between the steel reinforced concrete beam and the concrete filled steel tubular column is optimized.
本发明涉及一种型钢混凝土梁与钢管混凝土柱连接节点。型钢混凝土梁与钢管混凝土柱连接节点，包括钢管柱；横梁，钢梁连接头，有至少一对，同一对的两钢梁连接头位于钢管柱的两侧；每一对钢梁连接头均配置有上纵筋和下纵筋，所述上纵筋和下纵筋均沿相应的钢梁连接头设置并跨过钢管柱；对应于同一对钢梁连接头的上、下纵筋外部环绕有箍筋，并与箍筋一起形成钢筋笼。上、下纵筋和箍筋围成钢筋笼，上、下纵筋同时对应位于钢管柱相对两侧的钢梁连接头，即钢筋笼同时对应位于钢管柱相对两侧的钢梁连接头，可以通过钢筋笼将一部分弯矩传递至对侧，减小了钢梁和钢管柱的应力集中，优化型钢混凝土梁与钢管混凝土柱连接节点的受力。
