摘要：
According to the coordination equation of displacement between two system, spatial finite element model of curved continuous rigid frame bridge built by grillage method and whole vehicle model of 7 DOF, spatial numerical resolution of vehicle-bridge coupling was achieved. Then response curves of vehicle-bridge coupled vibration under different eccentric loads were obtained and dynamic coefficients of each web were solved. Compared with beam model, the results indicate that dynamic coefficients curves of each web under eccentric loads can be well simulated by grillage method and their differences also be reflected. So this method is universal and can be referenced by coupled vibration analysis of other complicated bridges.
