Background

At present, the bridge anti-seismic method mainly consumes seismic energy through plastic deformation selected by a structure, and prolongs the structure period, so that the seismic reaction is reduced, and the effect of resisting the seismic action is achieved. At present, bridge piers are usually designed into ductile members, so that the bridge piers are prevented from collapsing under the action of earthquakes, and the life and property safety of people is protected. However, for medium and low bridge piers, shear failure is likely to occur during earthquake action, and in order to avoid the shear failure, a large number of stirrups and longitudinal bars need to be arranged, which greatly increases the construction cost. And the ductility design dissipates seismic energy through the plastic deformation of the plastic hinge, so that the plastic hinge part of the pier is inevitably damaged, especially under the action of strong shock, the damage is more serious, the top of the pier has larger lateral displacement so as to fail to meet the normal function of the pier, and the pier is forced to be overhauled or dismantled for reconstruction, so that traffic is interrupted, and huge economic loss is caused.
