This research develops a three-dimensional computation code to analyze the vehicle-track-bridge interaction behaviors. The main object of this research is to apply the vector form intrinsic finite element (VFIFE, V-5) method to calculate the nonlinear dynamic response of bridge under the vehicle. The VFIFE method is used to simulate the vehicle, the track and the bridge. The VFIFE method can compute the motion of rigid body and deformable body for the vehicle. It can't require any iteration or any parameters during computation for solving the problems. In addition, using frame elements to model the shape of the vehicle is called vehicle model using frame elements (VMFE). The VMFE is used to simulate motion of a derailed carriage. In this paper, the VFIFE method provided an effective numerical method for the vehicle-track-bridge interaction behaviors.
