Abstract

In order to make full use of the advantages of large construction tolerance of socket piers and the self-resetting ability of unbonded prestressed piers after earthquakes, and reduce the on-site prestressed tensioning construction, a hybrid connection prefabricated pier connected by socket connection and factory pretensioned unbonded prestressed reinforcement is proposed. The three-dimensional finite element model of the bridge pier was established by ABAQUS software. The accuracy of the numerical model was verified based on the quasi-static test results. The local damage, hysteretic behavior, skeleton curve, energy dissipation capacity, prestressed tendon tension, joint opening and other behaviors of the bridge pier were analyzed. The results show that the numerical model established in this paper can reproduce the quasi-static results well, and the force-displacement curve of the precast pier with hybrid connection is "flag type"; When the deviation rate of pier top is 5%, only transverse cracks appear on the pier column, without other obvious structural damage; When the socket depth is 0.4D, the cap has slight cracks, and when the socket depth is 0.7D, the cap can provide sufficient uplift resistance without obvious damage; There is stress concentration in the outer steel pipe and steel backing plate.
