This paper investigates the seismic response of curved beam bridges equipped with friction pendulum isolation bearings through nonlinear time history analysis. Various influencing factors are considered, including different bearing schemes, friction coefficients, and slide radii of the friction pendulum isolation bearings. The results demonstrate that the use of friction pendulum bearings significantly reduces the internal force and displacement responses of the curved beam bridge. The effectiveness of isolation is closely related to the location and number of bearings. For curved beam bridges with variable height piers, the friction pendulum bearings exhibit better isolation performance in the tangential direction compared to the radial direction. Both the friction coefficient and slide radius of the bearings influence the seismic response of the curved bridge. The influence of the friction coefficient on the seismic performance of the bridge is more pronounced compared to the slide radius of the bearing. The selection of an appropriate friction coefficient not only controls the internal force of the bridge but also mitigates the displacement response.
