Integral abutment-H-shaped steel pile node anti-seismic structure locally using rubber concrete
The invention discloses an integral abutment H-shaped steel pile node anti-seismic structure locally using rubber concrete, which comprises an abutment and an H-shaped steel pile embedded into the abutment along the length of the abutment, and the rubber concrete embedded into the concrete abutment is poured on the periphery of the top of the H-shaped steel pile. And the strength of the rubber concrete is basically consistent with that of concrete forming the abutment. Ordinary concrete can be alternately arranged with the rubber concrete in the length direction of the abutment, or corrugatedsleeves are arranged between the rubber concrete and the side face of the abutment. According to the integral abutment H-shaped steel pile node anti-seismic structure, the rotating capacity of the integral abutment H-shaped steel pile node is improved, the lateral rigidity is reduced, the allowable horizontal displacement of a top structure in the longitudinal direction of a bridge is increased, the ductility and crack resistance of concrete at the integral abutment H-shaped steel pile node are improved, and the anti-seismic property of the node is improved. The use of the rubber concrete is beneficial to solving the problems of environmental protection and resource shortage caused by waste rubber, and the social effect is remarkable.
本发明公开了一种局部使用橡胶混凝土的整体式桥台‑H型钢桩节点抗震构造，包括桥台和沿桥台的长度嵌入至桥台内的H型钢桩，H型钢桩顶部的外周浇筑有嵌入至混凝土桥台内的橡胶混凝土，橡胶混凝土的强度与构成桥台的混凝土的强度基本一致。沿桥台长度方向与橡胶混凝土可以交替的设有普通混凝土或是在橡胶混凝土与桥台的侧面之间设有波纹套管。本发明的节点抗震构造提高了整体式桥台‑H型钢桩节点的转动能力，降低了侧向刚度，增大了顶部结构的纵桥向容许水平位移量，提高了整体式桥台‑H型钢桩节点处混凝土的延性及抗裂性能，改善了节点的抗震性能。橡胶混凝土的使用有利于解决废弃橡胶所带来的环保和资源缺乏问题，社会效应显著。
