Bridge toughness damping limiting device
The invention discloses a bridge toughness damping limiting device, and belongs to the technical field of bridge seismic resistance. According to the bridge toughness damping limiting device, one end of a traction piece is fixed to the bottom of a bridge girder; the other end of the guide piece is fixed at the top of the pier; a first hinge assembly and a second hinge assembly of the damping part are elastic assemblies and are symmetrically distributed on the two sides of the guide rod, and the ends, close to the traction piece, of the first hinge assembly and the second hinge assembly are hinged to the traction piece. The ends, close to the guiding piece, of the first hinge assembly and the second hinge assembly are hinged to the guiding piece. When the traction piece gets close to the guide piece, the first hinge assembly and the second hinge assembly can deform along with movement of the traction piece. According to the tough damping limiting device for the bridge, the axial rigidity of the device is reduced through linkage deformation of the traction piece, the hinge piece and the elastic beam, so that the seismic oscillation transmissibility of the device is reduced, and the upper structure of the bridge is protected.
本发明公开了一种桥梁韧性减震限位装置，属于桥梁抗震技术领域。该桥梁韧性减震限位装置包括包括牵引件一端固定在桥梁主梁底部；导向件一端与牵引件滑动连接，另一端固定在桥墩顶部；减震部的第一铰接组件和第二铰接组件均为弹性组件，第一铰接组件和第二铰接组件对称分布在导向杆的两侧，且第一铰接组件和第二铰接组件靠近牵引件的一端均与牵引件铰接，第一铰接组件和第二铰接组件靠近导向件的一端均与导向件铰接；当牵引件靠近导向件时，第一铰接组件和第二铰接组件能跟随牵引件的移动发生形变。本发明的桥梁韧性减震限位装置，通过牵引件、铰接件、弹性梁的联动变形，降低装置的轴向刚度，从而降低装置对地震动的传递率，保护桥梁上部结构。
