Summary

In this paper a number of representative high-speed railway bridges are evaluated by assessing the influence of the different vehicle models usually employed for dynamic analysis under the action of vertical travelling loads. Particular, attention is focussed on the importance of vehicle-bridge interaction effects with respect to the evaluation of the maximum vertical acceleration of the deck. The additional damping method, developed by the ERRI D214 committee and included in Eurocode 1, was devised to include these effects (in a simplified way) when the analysis is to be carried out with constant load models. A number of representative simply-supported bridges and three different high-speed trainsets were selected for comparing the predictions given by the additional damping method and the most popular vehicle-bridge interaction models. The discrepancies between the results obtained with the different methods are investigated, and their consequences in the evaluation of the maximum deck acceleration (a key factor for the design of simplysupported structures) are presented and discussed.
