Full-Scale Testing of a Model Structure in Euroseistest To Study Soil-Foundation-Structure Interaction

Abstract eng:
A large experimental campaign to study soil-foundation-structure interaction and wave propagation in soil media due to structural oscillation is presented in the largescale experimental facility of EuroSeistest in Greece, where a real-scale model structure (EuroProteas) was recently constructed. The structure was especially designed to promote soil-foundation-structure interaction taking into account the well-known foundation soil at site. Six experimental campaigns were performed: three pull-out (free-vibration) and three forced-vibration sets of tests. Pull-out was performed with a counterweight and the total pullout force exceeded 15kN. Forced-vibration sine sweep tests were performed using an eccentric mass vibrator and total force exceeded 20kN. The vibrator was placed both on the foundation and the top of the structure. Response was recorded by a dense 3D array composed of more than 80 recording devices (accelerometers, seismometers, shape acceleration arrays). In this paper we present the recorded response from selected tests, highlighting soilfoundation-structure effects in the structure and in the soil.
