Interaction dynamics of a high-speed train moving on multi-span railway bridges with support settlements

Original language description

After construction of rail bridges, differential support settlement at bridge foundations is one of the key issues being considered for running safety of trains and operation of railways. In this paper, the influence of ground settlement on dynamic interactions of train-bridge system will be studied. The train is simulated as a sequence of identical sprung mass units with equal intervals and the bridge system as a series of simple beams with identical properties. To resolve the train-induced vibrationsof a beam structure with support settlements, the total beam response is decomposed into two parts: the static response due to vertical support settlement and the dynamic component caused by inertia effect of beam vibration. An exact solution for staticdisplacement is presented by exerting the support displacements on the beam statically. Thus the remaining dynamic response of the vehicle/bridge coupling system can be computed by conventional vehicle-bridge interaction dynamic method. F
