Abstract: Designing foundations for o shore wind turbines (OWT's) are challenging, in order to ensure reliable and cost-e ective designs, the e ects of the support structure and the subsoil on the natural vibration characteristics have to be taken into account during the dynamic simulation of the structural response. The focus of this work is to evaluate the in uence of the multi-layered strata on the magnitude of the soil-structure interaction (SSI) of gravity-based structure (GBS) foundations. To do so, a simpli ed model is proposed for the computation of impedance functions including the SSI e ects. The result will be obtained using 3D boundary element program "BEASSI" and "SAP2000".
