In this paper the effects of the soil-structure interaction (SSI) on dynamic response of reinforced-concrete (RC) buildings of different heights are analyzed. Two 3D numerical models of 5 and 10-storey reinforced-concrete buildings founded on two different foundation types: plate and single foundations, lying on two types of soils: soft and stiff ones, are considered. Two types of the dynamic analysis are carried out: time history analysis and response spectrum method. The obtained results are compared. Ten earthquake records chosen for Belgrade site are used. The wave propagation in the soil is taken into account using the originally coded MATLAB program. The appropriate conclusions are derived according to the obtained results.
