Prefabricated swing pier structure system with additional energy dissipation support or self-resetting energy dissipation support
A prefabricated assembly type swing pier structure system with an additional energy dissipation support or a self-resetting energy dissipation support belongs to the technical field of seismic mitigation and isolation of bridge engineering, and mainly comprises a prefabricated bearing platform, a prefabricated pier column, a prefabricated cover beam, a prefabricated support and a resetting rib, two bearing platform sleeves are arranged on the prefabricated bearing platform and are used for connecting the two lower lug plates; column sleeves are arranged at the upper part and the lower part of the prefabricated pier column; a cover beam sleeve is arranged in the middle of the prefabricated cover beam and used for being connected with an upper lug plate. The prefabricated support is arranged between the lower lug plates and the upper lug plate and is hinged through a pin; the reset rib penetrates through holes reserved in the prefabricated bearing platform, the prefabricated pier column and the prefabricated cover beam, and are fixedly connected to the lower end of a platform body of the prefabricated bearing platform and the upper end of a beam body of the prefabricated cover beam through a high-strength bolt and a groove-shaped steel gasket. In the earthquake process, the whole system swings, the bending moment of the top and the bottom of the pier column is released, and plastic hinges at joints are avoided.
一种附加耗能支撑或自复位耗能支撑的预制装配式摇摆桥墩结构体系，属于桥梁工程减隔震技术领域，主要包括预制承台、预制墩柱、预制盖梁、预制支撑、复位筋；预制承台上设有两个承台套筒，用于连接两个下耳板；预制墩柱上部和下部均设有柱套筒；所述预制盖梁中部设有盖梁套筒，用于连接上耳板；所述预制支撑设置在下耳板和上耳板之间，通过销钉实现铰接；所述复位筋贯穿预制承台、预制墩柱和预制盖梁预留的孔洞，并在预制承台台身下端和预制盖梁梁身上端通过高强螺栓和凹槽形钢垫片固定连接。地震过程中整个体系产生摇摆，释放了墩柱柱顶和柱底弯矩，避免了节点处塑性铰的出现。
