The seismic analysis model of a vehicle-rail-bridge installed with friction pendulum bearing was established.The OpenSees platform was used to analyze the nonlinear vibration of the bridge.The vehicle model considered the effects of the lateral stopper and the nonlinear damping in the secondary suspension.The Hertz wheel-rail contact relation was adopted to simulate the wheel-rail separation and collision.The number of degree-of-freedom of the rail structure was significantly reduced by using the Rayleigh-Ritz method.The vehicle-rail-bridge system was solved by a multi-time step explicit-implicit integrated algorithm.The study shows that the friction pendulum reduces the deck acceleration, but increases the deck displacement.It is found that the simply supported beam bridge installed with pendulum bearing reduces the vehicle acceleration, wheel-rail displacement and lateral forces significantly.Thus, the pendulum bearing is favorable for the vehicle safety on the simply supported beam during earthquakes.
