The experimental data are then compared to the results of the numerical simulation. By representing the base forces by surface point seismic sources, the induced wavefield radiated in the surrounding free field is then computed by numerical Green's functions. The results presented here do validate the numerical computation method, which gave distant motions in close relation with the experimental data, from a qualitative and quantitative point of view. The spectral analysis does also exhibit surface waves trapped in the topmost layer.
Results confirm the significant contamination of ground motion due to building vibration.
