Analysis on Vehicle-Bridge Coupling Vibration of FRP Deck and Steel Girders Bridge

摘要整理

The FRP slab bridge in this paper is modeled using the finite-element method to predict its modal characteristics. The interaction between the vehicle and the bridge is simulated by using a 3D vehicle-bridge coupled model considering the roughness of the bridge road surface. The dynamic response of the bridge is obtained in the time domain by using an iterative procedure employed at each time step. The influences of vehicle velocity, vehicle rigidity, and bridge surface roughness are investigated.
