Abstract

Based on a simple mechanical model, the dynamic response of a railway bridge crossed by a high-speed train is analyzed. The bridge structure is represented by an Euler-Bernoulli beam resting at both ends on spring-damper elements, which model the viscoelastic flexibility of the soil below the bridge foundations. The train is simplified by its axle loads, which cross the beam at constant speed. The influence of the train on the structure during the approach phase and after departure is considered. In an application example the effect of the train speed, the subsoil conditions and the type of train on the peak acceleration of a ballasted bridge is studied.
