The importance of the structural piles has been determined on the seismic response of the site based on the analytical, numerical and laboratory studies. Due to the lack of laboratory or the numerical studies with the support of laboratory studies, the results are limited to the specific conditions, and problems with the simple geometry and elastic behaviors of the materials against the shear waves in frequency domain. Many studies have been done on the effect of kinematic and inertial interactions on the seismic responses of the soil-pile system by numerical methods. However, most numerical studies based on the results of the analytical methods, and the numerical studies have had less laboratory support. Therefore, this study investigates the effects of the kinematic and inertial interaction of the pile-soil on the dynamic response of a single pile, using physical modeling of a pile in the dry sandy soil with shaking table along with the numerical modeling verified by the laboratory results in ABAQUS FEM software simulation. Moreover, using the numerical models the effect of soil characteristics such as: the modulus of elasticity, how it is distributed in soil, pile capping etc. has been studied. It can be deduced that fix pile head with cap and soil specification, such as the modulus of elasticity, have a great impact on the distribution and the maximum amount of bending moment along the pile.
