The analysis of the seismic response of soil-pilestructure systems constitutes a complex problem in earthquake engineering. Previous studies showed that the damage of piles in seismic area is mainly attributed to the kinematic interaction between piles and soils or (and) to the inertial interaction between the superstructure and the pile foundation which may cause foundation damages. In this paper we present a global numerical modeling of the pile-foundation-pile-cap-structure interaction using FLAC3D Software. The study is conducted by using measures recorded during real earthquakes. The influence of plasticity is investigated for cohesive soils where the soil behaviour is described using Mohr–Coulomb criterion. Moreover, the efficiency of inclined piles in seismic zones is commented, and a parametric study according to piles inclination is also performed. The analysis of the results could give the best piles group configuration in order to minimize the seismic effect on the structures.
