At present, the bridge structure with easily controllable earthquake damage and high maintenance and replacement speed is developed, and has important significance for improving the earthquake-proof and disaster-reducing capacity of the underdeveloped mountain road network.
Bent piers are very common in highway bridges, however, pier column-transverse tie beam joints are vulnerable positions under the action of earthquakes, and plastic hinges are common in joint areas, column ends or beam ends in the joint areas, so that the whole bearing capacity of the piers can be reduced or collapsed when the bridge is seriously damaged, and the traffic function is lost. In addition, even though the pier column-tie beam of the traditional bent pier has beam end plastic hinges expected by ductility design under the action of earthquake, the steel bar yield or buckling of the pier column-tie beam still causes structural restoration and difficult concrete restoration.

The middle part of the bent steel plate 12 is bent to bear the axial tension and the axial pressure generated by the beam end bending moment of the tie beam 2 in a normal use state or under the action of an earthquake. The anti-buckling device 10 is used for preventing the non-bending section steel plate of the bending steel plate 12 from buckling in the compression process, but the anti-buckling device 10 does not participate in the compression process.
As shown in fig. 5, the bent shape of the bent steel plate 12 is a triangular bent shape, the bent positions of the bent steel plates 12 at the upper and lower edges of the tie beam 2 are arranged in a staggered manner, and a space exists between the vertical planes at the vertexes of the triangular bent shapes of the upper and lower bent steel plates 12, so that the excessively low rigidity and bearing capacity on the same section can be avoided.
The buckling restrained device 10 includes: a wide restraint cover 13 and two narrow restraint cover 14.
