Improved integral abutment-H-shaped steel pile node anti-seismic structure adhered with rubber plates
The invention discloses an improved integral abutment H-shaped steel pile joint anti-seismic structure adhered with rubber plates. The structure comprises an abutment and an H-shaped steel pile, the upper portion of the H-shaped steel pile is embedded into the abutment along the length of the abutment, and the rubber plates are arranged between the H-shaped steel pile embedded into the abutment and the abutment. The abutment is a concrete bridge abutment formed by concrete poured on the peripheries of the rubber plates. And the rubber plates are adhered to the peripheries of webs and flange plates of the H-shaped steel piles embedded into the abutment. The depth of the H-shaped steel pile embedded into the concrete bridge abutment is determined according to sufficient anchoring provided for the H-shaped steel pile. The node anti-seismic structure allows the steel piles and the abutment to relatively rotate to a certain degree, and the allowable longitudinal horizontal displacement of the top structure is increased. According to the node anti-seismic structure, the vertical bearing capacity can be guaranteed, meanwhile, the lateral rigidity is reduced, the structural ductility is improved, the longitudinal-bridge-direction horizontal displacement of the bridge body can be well absorbed, and the anti-seismic property and the energy consumption property of the node are improved.
本发明公开了一种贴橡胶板改进的整体式桥台‑H型钢桩节点抗震构造，包括桥台和H型钢桩，H型钢桩的上部沿桥台的长度嵌入至桥台内，在嵌入桥台部分的H型钢桩与桥台之间设有橡胶板，桥台是由浇筑在橡胶板外周的混凝土构成的混凝土桥台。橡胶板粘贴在H型钢桩嵌入桥台部分的腹板与翼缘板周边。H型钢桩嵌入混凝土桥台的深度按照提供给H型钢桩足够锚固来确定。本发明的节点抗震构造允许钢桩与桥台能发生一定程度的相对旋转，增大了顶部结构的容许纵向水平位移量。本发明的节点抗震构造能够在保证竖向承载力的同时，降低侧向刚度，改善结构延性，可很好地吸收桥身的纵桥向水平位移，改善节点的抗震性能和耗能性能。
