Descrição: dc.descriptionThe present work focuses on the evaluation of the dynamic behavior of a centenary steel arch bridge, located in Portugal, under light railway tra±c loads. This works aims to assess the dynamic behavior of the bridge subjected to an alternative type of railway vehicle, more speci ̄cally, a typical underground vehicle that is currently in service in the Lisbon Metro. The dynamic response of the system has been evaluated using two distinct methodologies, namely a moving loads model and a vehicle–bridge interaction model. To achieve this goal, ̄nite element (FE) models from both the bridge and the vehicle have been developed and a comprehensive study has been carried to evaluate the in°uence of distinct factors in the dynamic response of the bridge–train system, namely the methodology used to assess the dynamic response, the location of the response reference point in the deck, the train speed and the vehicle con ̄guration (single or double vehicle). Moreover, both the tra±c safety, passenger comfort and pedestrian comfort have also been evaluated using normative criteria based on acceleration responses. The results shown that the normative limits related to tra±c safety and passenger comfort were never exceeded in any condition analyzed in the study. However, the pedestrian comfort was jeopardized when the train speed exceeded 20 km/h.-
