Transverse complete self-resetting damping system for large-span bridge in strong earthquake area
The invention discloses a transverse complete self-resetting damping system for a large-span bridge in a strong earthquake area. The transverse complete self-resetting damping system comprises two bridge tower columns which are oppositely arranged in the transverse direction of the bridge; the bridge tower cross beam is connected between the two bridge tower columns; the main beam is arranged above the bridge tower cross beam; the fixing assembly is arranged at the bottom of the main beam, the fixing assembly comprises two groups of anchoring blocks, and each group of anchoring blocks comprises two anchoring blocks which are symmetrically arranged; the FRP cable assembly comprises two groups of FRP cables, each group of FRP cables comprises two symmetrically arranged FRP cables, the FRP cables are made of FRP materials, one ends of the FRP cables are anchored on the tower columns of the bridge tower, and the other ends of the FRP cables are anchored on the anchoring blocks; one end of the transverse viscous damper is anchored at the top end of the bridge tower cross beam, and the other end of the transverse viscous damper is anchored at the bottom end of the main beam. Based on the cooperation of the FRP cable and the transverse viscous damper, the transverse viscous damper has the characteristics of large bearing capacity, large deformation capacity and complete reset capacity, and the performance of a large-span bridge under the strong earthquake condition can be remarkably improved.
本发明公开了一种强震区大跨度桥梁横向完全自复位减震体系，包括：沿横桥向相对设置的两个桥塔塔柱；桥塔横梁，桥塔横梁连接于两个桥塔塔柱之间；主梁，设置于桥塔横梁上方；固定组件，设置于主梁底部，固定组件包括两组锚固块，每组锚固块包括对称设置的两个锚固块；FRP索组件，FRP索组件包括两组FRP索，每组FRP索包括对称设置的两个FRP索，FRP索采用FRP材料制成，FRP索的一端锚固于桥塔塔柱上，另一端锚固于锚固块上；横向粘滞阻尼器，所述横向粘滞阻尼器的一端锚固于桥塔横梁的顶端，另一端锚固于主梁的底端。本发明基于FRP索和横向粘滞阻尼器的配合，兼具大承载力、大变形能力和完全复位能力的特点，能够显著提高强震条件下的大跨度桥梁的性能。
