Abstract
In this paper, the preliminary results concerning the fatigue assessment of Lagoscuro railway viaduct is described. First, experimental dynamic tests have been performed in order to identify the modal properties. Then, a FE model is corrected with a model updating procedures, where the uncertain model properties are adjusted in order to have the numerical predictions as close as possible to the measured data. Making use of the FE model, a preliminary fatigue assessment is carried out following the procedure defined in EN1993.
