Abstract

With a purpose to overcome the problem of lower load-bearing capacity and more complex assembly process of socket-connected bridge piers, this paper proposes a new type of tenon-core socket precast pier with ultra-high performance concrete as the connecting material, and carries out the quasi-static tests of three different structural specimens, and the results show that: the specimen of the plastic hinge area of the connecting joints of the bridge pier adopting UHPC has a higher yield bearing capacity, maximum bearing capacity, and ultimate bearing capacity than that of the specimen adopting C40 concrete, which are 13.19%, 18.8%, and 27.87% higher, respectively. The results of finite element analysis show that the ABAQUS finite element model can accurately simulate the plastic damage of the specimen, and the hysteresis curve and skeleton curve are more consistent with the test results.
