Multi-column-pier section type energy dissipation bent cap structure and design method thereof
The invention belongs to the technical field of bridge engineering, and provides a multi-column-pier segmental energy-consuming bent cap structure which comprises a plurality of segmental bent caps, each segment is supported by at least one column pier at the bottom of the segment, and the multi-column-pier segmental energy-consuming bent cap structure is characterized in that an energy-consuming assembly is arranged between every two adjacent bent caps, and each energy-consuming assembly comprises a metal shear energy-consuming device 102, a metal shear energy-consuming device 104 and a metal shear energy-consuming device 106. Connecting pieces 101 are embedded in the opposite ends of the adjacent cover beams, the inward ends of the connecting pieces 101 are perpendicularly and fixedly connected with first connecting steel plates 103-1, the left end and the right end of the metal shear energy dissipation device 102 are perpendicularly and fixedly connected with second connecting steel plates 103-2, and the second connecting steel plates 103-2 on the left side and the right side are detachably connected to the first connecting steel plates 103-1 through bolts 104. The shearing rigidity of the metal shearing energy dissipation device 102 is smaller than that of the bent cap. By introducing the energy dissipation assembly, deformation decoupling of the pier columns in the multi-column pier is achieved, the length of the bent cap is reduced, and seismic damage control and construction quality of the multi-column pier can be improved.
本发明属于桥梁工程技术领域，提供了一种多柱墩节段式耗能盖梁结构，其包括多个节段式盖梁，每个节段通过其底部至少一个柱墩支撑，其特征在于：相邻两个盖梁之间均设有耗能组件，单个耗能组件包括金属剪切耗能装置102，相邻盖梁相对端部均嵌设有连接件101，连接件101朝内端均垂直固定连接第一连接钢板103‑1，金属剪切耗能装置102的左右两端垂直固定连接第二连接钢板103‑2，左右侧的第二连接钢板103‑2通过螺栓104可拆卸连接于第一连接钢板103‑1，金属剪切耗能装置102的剪切刚度小于盖梁的剪切刚度。本发明通过引入耗能组件，实现了多柱墩中墩柱变形解耦，减小了盖梁长度，有利于提升多柱墩的震损控制和建造品质。
