Abstract: FPS support is a seismic isolation bearing with broad development prospects. The support can absorb the ground motion energy input of a structure during an earthquake by friction energy consumption and self-recentering characteristics, thus greatly reducing the structural seismic response. However, at present, there is a lack of a refined theoretical and experimental simulation method for the coupling force problem of curved bridge FPS bearings at home and abroad. In this paper, a quasi-static test is carried out by two-way loading of FPS bearings. The load-displacement hysteresis curves and frictional energy consumption of the FPS bearings are obtained. The OpenSees software is used to simulate the FPS bearings. The test results are compared with the numerical simulation results to verify the accuracy. A refined simulation method of FPS bearings is obtained.
