Self-resetting damping device and bridge self-resetting system
The invention provides a self-resetting damping device and a bridge self-resetting system, the self-resetting damping device is connected between a main beam and a bridge pier, the self-resetting damping device comprises an outer pipe, one end of the outer pipe is connected with the main beam, the outer pipe is internally provided with a resetting section and an energy consumption section, the resetting section is internally provided with an elastic piece, and the energy consumption section is internally provided with a damping piece; one end of the inner pipe is connected with the pier, and the other end of the inner pipe is arranged in the elastic piece and the damping piece in a penetrating mode; and when the inner pipe and the outer pipe are close to each other or far away from each other, the elastic piece is compressed in the reset section. According to the self-resetting damping device, the problems of large internal force, remarkable displacement response and large residual displacement after an earthquake of a main body structure of an existing railway bridge can be solved.
本发明提出一种自复位减震装置和桥梁自复位系统，自复位减震装置连接在主梁与桥墩之间，其包括：外管，其一端与所述主梁连接，所述外管内具有复位段和耗能段，所述复位段内设有弹性件，所述耗能段内设有阻尼件；内管，其一端与所述桥墩相连，所述内管的另一端穿设在所述弹性件和所述阻尼件中；其中，在所述内管与所述外管相互靠近或相互远离的状态下，所述弹性件在所述复位段内被压缩。本发明所述的自复位减震装置能够解决目前铁路桥梁存在的主体结构震时内力大、位移响应显著，震后残余位移大的问题。
