Modern regulations require from engineers to take into account a non-linear behavior and the appearance of plastic hinges in the selected structural elements during the earthquake. Also, regulations more insist on considering the soil-structure interaction (SSI) in the computation of dynamic response of buildings. In this paper, the nonlinear time history analysis of multi-storey RC frame structure is carried out taking into account SSI according to the Eurocode 8 and FEMA 450 recommendations. In order to illustrate the impact of the SSI, the response of the structure is calculated with and without the influence of the soil. Nine accelerograms are selected to correspond to the frequency spectra defined in EC8. Two standard types of soil, (ie. type B and C) according to the EC8, are adopted. The appropriate conclusions and recommendations for further work in this area are carried out.
