Pier-beam hinged non-penetrating type prestress self-resetting bridge anti-seismic system
The invention discloses a pier-beam hinged non-penetrating type prestress self-resetting bridge anti-seismic system, and belongs to the technical field of bridge engineering. Comprising a main beam, a pier, a pier bottom reduced-scale area and a pedestal which are sequentially connected from top to bottom, a hinge structure is arranged at the top connecting position of the main beam and the pier, an anti-sliding structure is arranged on the outer side of the connecting position of the pier bottom reduced-scale area and the pedestal, and a plate type energy consumption device is arranged on the outer side of the pier bottom reduced-scale area. One end of the plate-type energy consumption device is connected with the pier, the other end of the plate-type energy consumption device is connected with the pedestal, a plurality of unbonded prestressed steel strands for connecting the pier and the pedestal are arranged in the circumferential direction of the pier and the pedestal, one end of each unbonded prestressed steel strand is fixedly connected to the pier, and the other end of each unbonded prestressed steel strand is fixed to the pedestal. The technical scheme is used for solving the problem of how to improve the anti-seismic property of the bridge and ensure the repairability after an earthquake.
本发明公开了墩梁铰接非贯穿式预应力自复位桥梁抗震体系，属于桥梁工程技术领域。包括从上往下顺次连接设置的主梁、桥墩、墩底缩尺区域和台座，所述主梁于桥墩的顶部连接部位设有铰接构造结构，所述墩底缩尺区域与台座的连接部位外侧设有抗滑移构造结构，所述墩底缩尺区域外侧设有板式耗能装置，所述板式耗能装置的一端与桥墩连接，另一端与台座连接，所述桥墩与台座的周向设有若干将二者连接的无粘结预应力钢绞线，所述无粘结预应力钢绞线的一端固定连接于桥墩上，另一端固定于台座上。本技术方案用以解决如何提高桥梁的抗震性能及保证震后可修复的问题。
