Dynamic Response of High Speed Train Moving on Consecutive Bridges
Abstract This research demonstrates how to analyse the dynamic response of a high-speed train moving over consecutive bridges. The authors explain in detail how to apply the uncoupled iterative method to consecutive bridges, by deriving the complete motion history for one bridge segment at a time, using the solution of the train as an initial condition for the next bridge. This algorithm is a highly cost-effective approach to analysing the train-bridge interaction for a high speed railway (HSR). The authors perform this analysis on two existing bridges: a simply supported Taiwan HSR bridge, and a three-span continuous Korea HSR bridge. The results show that both types of bridges are capable of supporting HSR trains at speeds up to 400 km/h with negligible carbody displacements and accelerations. This speed is greater than the current service speed of 300 km/h.
