The purpose of this study is to establish a reliable and effective analytical procedure to simulate the dynamic response of the high-speed railway bridge-train-earthquake interaction system, so as to investigate the running stability of the bullet train and the earthquake performance of the elevated bridge. As a preliminary effort to realize the final goal aforementioned, exploying a developed 15-degree-of-freedom bullet train model and a three-dimensional finite element bridge model, a three-dimensional dynamic response analysis of the Shinkansen bridge-train interaction system under seismic load is carried out within the elastic range of the structures in this paper. The validity of the bridge-train and the accuracy of the seismic analysis algorithm is validated by comparing with the results of a general program.
