In this paper the effect of temperature variation on the structural response of a railway bridge is analysed. In particular the main goal consists of clearing the measurements from the temperature effects. The approach pursued in this work is to use the field data to calibrate a numerical model which sees the temperature time history as an external excitation. A different set of measurements is then used to validate the model. It should be emphasized that the train crossing effects are taken into account in a separated manner from the environmental ones. The structure under study is the ÖBB Brucke Großhaslau railway bridge, in Austria.

Abstract
In this paper the effect of temperature variation on the structural response of a railway bridge is analysed. In particular the main goal consists of clearing the measurements from the temperature effects. The approach pursued in this work is to use the field data to calibrate a numerical model which sees the temperature time history as an external excitation. A different set of measurements is then used to validate the model. It should be emphasized that the train crossing effects are taken into account in a separated manner from the environmental ones. The structure under study is the ÖBB Brucke Großhaslau railway bridge, in Austria.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
