Recently, for the long-period ground motions by the Tokai earthquake, the Tonankai earthquake, et al., the safety of various structures becomes a problem. In this paper, Using the analytical model of high-speed moving railway vehicles proposed by Shintani, et al., its dynamic behavior is studied by use of the artificial ground motions, artificial log-period ground motions and actual ground motion in horizontal and vertical directions simultaneously. From the analytical results, some correlation effects between the horizontal ground motion and vertical ground motion on the possibility of rollover of the vehicle are shown. Also, it is clear that the possibility of rollover of the vehicle is small for the long-period ground motions used in this study.
