Abstract: Soil-structure interaction depends on the mass, stiffness and the damping of the structure as well as on the geometry and embedment of the foundation and on the properties of the soil. The total response of the structure will on the other hand be essentially influenced by the frequency content of the loading. In this paper, the structure embedded on a layer on top of a half-space is excited by an earthquake. The motion of the earthquake is assumed to arise from vertically incident SV-waves. Using the substructure method the structure is discretized by FEM, the subgrade by BEM. The two parts of the motion, i. e. the kinematic and inertial part, are given separately to show the influence of the scattered field. Results are calculated in frequency and time domain.
