The paper deals with a simultaneous effect of a row of regularly distributed moving loads and a vertical seismic ground excitation on a single-span bridge. The simple mathematical model is used to allow direct comparison of analytical and numerical results. Advantages and drawbacks of both methods are discussed. Various levels of simplification of description the loads are supposed. The discussed methodology is illustrated on an example of an interaction of the real concrete bridge, the high-speed train TALGO AV2 and an artificial earthquake data.
