Gecko-type tough bridge seismic mitigation and isolation device
The invention discloses a gecko-type tough bridge seismic mitigation and isolation device, and belongs to the technical field of bridge seismic mitigation and isolation. The gecko-type tough bridge seismic mitigation and isolation device is symmetrically arranged at the top of the bridge pier in the longitudinal bridge direction and connected with the bottom of the main beam, and when the bridge is subjected to longitudinal earthquake action, the bridge pier displaces to drive the first combined assembly and the second combined assembly in the gecko-type tough bridge seismic mitigation and isolation device to do reciprocating tension and compression motion; when the first traction rod and the second traction rod are pressed, the elastic beam assembly can generate geometric linear deformation and bending deformation, so that the rigidity of the gecko-type tough bridge seismic reduction and isolation device in the axis direction is reduced, the natural vibration period is prolonged, the transmission rate of the device to seismic oscillation is reduced, and damage in the longitudinal bridge direction is effectively prevented.
本发明公开了一种壁虎式韧性桥梁减隔震装置，属于桥梁减隔震技术领域。本发明提供的壁虎式韧性桥梁减隔震装置，沿纵桥向对称布置在桥墩顶部，并与主梁底部相连接，在桥梁受到纵向地震作用时，桥墩发生位移带动所述桥梁壁虎式韧性桥梁减隔震装置中的第一联合组件和第二联合组件做往复拉压运动，当第一牵引杆和第二牵引杆受压时，其会使弹性梁组件发生几何线性变形，弹性梁组件弯曲变形，使壁虎式韧性桥梁减隔震装置轴线方向刚度降低，自振周期延长，装置对于地震动的传递率降低，有效防止纵桥向破坏。
