Dynamic soil-pile interaction during earthquakes is an important phenomenon to be taken into account in the pile design in relatively weak soil conditions. In this paper, soil-pile interaction is treated in two phases, namely “kinematic interaction” and “inertial interaction”. A quasi-static engineering approach is developed for the analysis of kinematic interaction in which results of a nonlinear site response analysis is utilized for the determination of maximum free-field ground displacements and compatible shear moduli. The latter is then utilized to determine the lateral soil stiffness matrix. The effect of soil liquefaction is also considered through appropriate reduction of soil stiffnesses. On the other hand, inertial interaction is formulated on the basis of spectral response analysis where the same soil stiffnesses are utilized. Numerical results obtained from a design case study are presented demonstrating the significance of kinematic interaction which is generally neglected in the pile design practice.
