The response of piled-structures under earthquake loading is influenced by the interaction within soil, foundation system embedded in ground, and superstructure (“SFSI” soilfoundation-structure interaction). These interaction effects are typically classified into two distinct categories, namely inertial and kinematic. During an earthquake, the soil medium vibrates the piles and the superstructure, and the accelerated/mobilized masses of the piles and superstructure shake the soil back when inertial interaction is significant. Kinematic interaction, on the other hand, is the collective term given to the effects of the rigidity of piles, which usually is significantly larger than that of the soil, leading to alterations in the incoming seismic waves. Generally, in designing pile supported structures, soil-pile interaction is ignored and the structure system is analyzed assuming the superstructure rests on a rigid base or using factored motions obtained from free-field site response analysis. However, pile foundations embedded into the ground resist soil displacements emanating from dynamic loading, such as an earthquake, and change the response of the surrounding soil. In this study, the effect of presence of a single pile on foundation input motion used in seismic design is investigated parametrically for clayey soils by using a numerical model based on finite elements method with an advanced soil constitutive soil model (hypoplastic). Additionally, the performance of pile foundations under seismic loads is examined
