Dynamic analysis of the Rössjö railway bridge, located on the new Swedish high speed line, is carried out. A simple 2D finite element model is developed and the dynamic response to passing trains is studied. The model is updated by modifying the support stiffness and comparing the predicted response with measurements. Results show that measured deck accelerations are in good agreement with what was predicted from the updated model. To further increase the accuracy in the predicted response, a method based on Bayesian updating is proposed.
