Abstract: To address replacing prestressed tendons in unbonded prestressed self-centering piers, authors propose a new type of self-centering bridge structure with replaceable prestressed tendons. Its seismic response under near-fault earthquakes is still unclear. To analyze the seismic response of replaceable prestressed reinforcement self-centering double-column pier girder bridge under near-fault ground motion, a numerical model of curved prestressed tendon double-column rocking self-centering pier was built on OpenSEES platform. First, the numerical simulation of horizontal reciprocating quasi-static loading at the pier top was carried out, and the accuracy of the modeling method was verified by the quasi-static test results. Based on a 3×30 m continuous beam bridge in a city of Gansu Province, a numerical simulation model of a replaceable curved prestressed self-centering double-column pier continuous beam bridge and an ordinary concrete continuous beam bridge with conventional ductile seismic design were established. Three sets of near-fault seismic records were used as input, and the peak acceleration of ground motion was adjusted according to the site characteristics of the bridge. The dynamic time-history analysis of the two bridges was carried out to compare their seismic responses. Results show that under the action of E1 earthquake, the energy dissipation components of the self-centering double-column pier girder bridge do not yield, the concrete at the bottom of the pier of the ordinary concrete beam cracks and the longitudinal reinforcement does not yield. Under the action of E2 earthquake, the maximum drift ratio of the double-column self-centering beam bridge is reduced by 47.9%-67.2% and the residual drift ratio is reduced by more than 90% compared with the ordinary concrete beam bridge, which exhibits excellent self-centering capacity. The maximum residual drift ratio of ordinary concrete girder bridge reaches 0.51%, which is not conducive to post-earthquake repair. The replaceable curved prestressed tendon self-centering double-column pier bridge has excellent post-earthquake resilience, which is conducive to post-earthquake replacement and repair.
