Hybrid energy dissipation bridge seismic mitigation and isolation structure
The invention discloses a hybrid energy consumption bridge seismic mitigation and isolation structure which comprises a bearing platform and a bridge pier at the top of the bearing platform, a cover beam is arranged at the top of the bridge pier, a bridge is arranged at the top of the cover beam, and plastic hinges are connected between the bearing platform and the bridge pier and between the bridge pier and the cover beam; and seismic mitigation and isolation energy consumption devices are symmetrically and fixedly arranged between the cover beam and the bridge, and a limiting check block is fixedly arranged at the side end of the top face of the cover beam or in the middle of the cover beam. The bridge seismic mitigation and isolation structure can better integrate the advantages of a ductile seismic mitigation system and a seismic mitigation and isolation system, is low in manufacturing cost and can be used for various bridge working conditions.
本发明公开了一种混合耗能桥梁减隔震结构，包括承台，以及承台顶部的桥墩，所述桥墩的顶部设置有盖梁，盖梁的顶部设置有桥梁，所述承台与桥墩之间、桥墩与盖梁之间均连接有塑性铰；所述盖梁与桥梁之间对称的固定设置有减隔震耗能装置，盖梁的顶面侧端或盖梁的中部固定设置有限位挡块。本发明旨在提供一种能够较好综合延性抗震体系和减隔震体系的优势，造价低廉，能够用于多种桥梁工况的桥梁减隔震结构。
