Overview
In this research project the effects of soil structure interaction on the dynamic response of railway bridges was analysed using different modelling alternatives such as boundary element – finite element analyses in the time domain. Numerical conclusions were compared to experimental measurements performed on real structures both under ambient vibration and forced vibration, including resonant situations.

Results
Fundamental tendencies on the structural properties and dynamic response of the evolution of soil properties were derived for an ensemble of representative bridges, assuming simplified substructure geometries. Experimental campaigns were performed in order to characterise the soil and identify the bridge dynamic properties and its response under railway traffic, both under resonant and not resonant conditions.
