In this study we present preliminary numerical modeling of forced-vibration full-scale soil-foundation-structure experiments performed in the facility of EuroProteas; a particularly stiff model structure founded on soft soil, mobilizing strong soil-foundation-structure interaction (SFSI) effects during structural oscillation. EuroProteas’ outer dimensions are 3x3m in plan view and 5m high. Various model configurations are possible by reconfiguring structural mass and stiffness. Forced-vibration tests were performed by means of an eccentric mass vibrator referring to sine sweeps tests with loading frequency varying between 1Hz and 10Hz and a total harmonic force up to 20kN. The vibrator was mounted both on the foundation and the superstructure slab of the model. We present preliminary 3D numerical simulation of the forced-vibration field experiments with emphasis on the recorded soil response. Discussion follows upon the adequacy of 2D and 3D modelling of the experiments.

Abstract
In this study we present preliminary numerical modeling of forced-vibration full-scale soil-foundation-structure experiments performed in the facility of EuroProteas; a particularly stiff model structure founded on soft soil, mobilizing strong soil-foundation-structure interaction (SFSI) effects during structural oscillation. EuroProteas’ outer dimensions are 3x3m in plan view and 5m high. Various model configurations are possible by reconfiguring structural mass and stiffness. Forced-vibration tests were performed by means of an eccentric mass vibrator referring to sine sweeps tests with loading frequency varying between 1Hz and 10Hz and a total harmonic force up to 20kN. The vibrator was mounted both on the foundation and the superstructure slab of the model. We present preliminary 3D numerical simulation of the forced-vibration field experiments with emphasis on the recorded soil response. Discussion follows upon the adequacy of 2D and 3D modelling of the experiments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
