“…Theoretical studies of bridge vibrations caused by running trains have been actively carried out (Tanabe et al, 1993;Diana et al, 2000;Xia et al, 2001;Kawatani et al, 2004Kawatani et al, , 2006. Recently, efforts have also been made towards clarifying the seismic response of the BTI system.…”

This study is intended to evaluate the infl uence of dynamic bridge-train interaction (BTI) on the seismic response of the Shinkansen system in Japan under moderate earthquakes. An analytical approach to simulate the seismic response of the BTI system is developed. In this approach, the behavior of the bridge structure is assumed to be within the elastic range under moderate ground motions. A bullet train car model idealized as a sprung-mass system is established. The viaduct is modeled with 3D fi nite elements. The BTI analysis algorithm is verifi ed by comparing the analytical and experimental results. The seismic analysis is validated through comparison with a general program. Then, the seismic responses of the BTI system are simulated and evaluated. Some useful conclusions are drawn, indicating the importance of a proper consideration of the dynamic BTI in seismic design.

“…Efforts thus far made to develop source models include: those by Furuta et al [1] who, in an attempt to clarify the vibration properties of tracks with low coefficients of spring, developed a model for analyzing coupled bogie-track vibrations and reviewed the model's validity; and those by Kawatani et al [2] who analyzed vibrations of viaducts during the passage of trains using a combination of a three-dimensional car model and a three-dimensional finite element viaduct model and reviewed the validity of the combined method and vibration mitigation measures. Numerous studies have also been conducted on propagation models as well, including a series of studies on highspeed trains by Krylov [3] and a study by Kanda et al [4] on simulation of wave fields.…”
