Abstract

This paper investigates the derailment of high-speed trains moving on multispan simply supported bridges. A moving wheel finite element containing contact and separation modes was developed to simulate vehicle-bridge interaction problems under seismic loads. Rail irregularities and bridge-rail-train interactions were appropriately considered in the nonlinear finite element analysis, which indicates that the derailment coefficients are enlarged with the increase of train speeds for high-speed trains moving on multispan simply supported bridges. The accelerations of elevated bridge girders may be significantly magnified during the seismic load; moreover, gaps between simply supported girders during seismic loads will produce large derailment coefficients.
