Self-adaptive damping and anti-collision device for transverse bridge direction of long-span bridge
The invention belongs to the technical field of vibration control of engineering structures, and particularly relates to a self-adaptive damping anti-collision device for the transverse direction of a long-span bridge, which comprises the long-span bridge and the self-adaptive damping anti-collision device, bridge towers, a cross beam and a bridge deck form a main frame of the long-span bridge, the cross beam is mounted between the pair of bridge towers, and the bridge deck is mounted on the cross beam. A bridge deck slab is arranged above the cross beam, the self-adaptive damping anti-collision device is installed between the bridge deck slab and the cross beam, an upper bracket is installed at the bottom of the bridge deck slab, a lower bracket is installed at the top of the cross beam, and the top of the self-adaptive damping anti-collision device is hinged to the bridge deck slab through the upper bracket. The bottom of the self-adaptive damping anti-collision device is hinged to the cross beam through a lower bracket. The self-adaptive damping anti-collision device is additionally arranged between the bridge deck and the cross beam of the large-span bridge, so that the energy consumption of the damper is improved, the bottom shearing force of the structure is reduced, meanwhile, the development of large displacement is limited, the bridge deck is prevented from colliding with the bridge tower, the multi-performance level requirements of the large-span bridge are met, and the safety and reliability of the bridge are guaranteed.
本发明属于工程结构振动控制技术领域，具体涉及一种用于大跨桥梁横桥向的自适应减震防碰撞装置，包括大跨桥梁和自适应减震防碰撞装置，所述桥塔、横梁和桥面板组成大跨桥梁的主要框架，一对所述桥塔之间安装有横梁，所述横梁的上方设置有桥面板，所述自适应减震防碰撞装置安装在桥面板和横梁之间，所述桥面板的底部安装有上牛腿，所述横梁的顶部安装有下牛腿，所述自适应减震防碰撞装置的顶部通过上牛腿和桥面板铰接，所述自适应减震防碰撞装置的底部通过下牛腿和横梁铰接。本发明通过在大跨桥梁的桥面板与横梁之间增设自适应减震防碰撞装置，提高了阻尼器的耗能、减小了结构的底部剪力，同时限制大位移的发展、避免桥面板与桥塔发生碰撞，满足大跨桥梁的多性能水准需求，保证了桥梁安全可靠。
