High-speed rail bridge damping device capable of actively carrying out replacement repair after damage
The invention discloses a high-speed rail bridge damping device capable of actively performing replacement and repair after damage, which comprises a seismic mitigation and isolation support arranged at the top of a prefabricated pier column and damping units symmetrically arranged on two sides of the seismic mitigation and isolation support, and unit main bodies of the damping units are respectively connected and fixed with a beam body and the prefabricated pier column through pre-embedded components. The unit body comprises an initial energy dissipation component and a standby energy dissipation component parallel to the initial energy dissipation component, when the initial energy dissipation component is sheared and damaged, the standby energy dissipation component can automatically change the position to replace the supporting and energy dissipation effects of the initial energy dissipation component, self-repairing of the damping unit is conducted, a support is protected against damage caused by the earthquake effect, and therefore beam falling damage is avoided.
本发明公开了一种可在损伤后主动进行替代修复的高铁桥梁减震装置，包括设置于预制墩柱顶部的减隔震支座，及减隔震支座两侧对称布置的减震单元，减震单元的单元主体分别通过预埋组件与梁体和预制墩柱连接固定。单元主体包括初始耗能构件和与其平行设置的备用耗能构件，初始耗能构件被剪切破坏时，备用耗能构件能自动改变位置来替代初始耗能构件的支撑及耗能作用，进行减震单元的自修复，保护支座不受地震作用破坏，从而避免落梁破坏。
