The acquisition of response data from large structures and surrounding sites during earthquakes is essential to determine the effect of local soil conditions on seismic ground motion and consequently on the structure's response. This paper studies the local soil effects on the ground motion based on recordings from a permanent accelerometer array installed on the cable-stayed bridge of the Evripos channel in Greece. Furthermore, the dynamic characteristics of the bridge using analytical and experimental methods, which include geodetic monitoring techniques, are investigated in order to provide a more realistic modelling of the bridge. This can result in reliable predictions of the bridge response in future earthquake excitations.
