The paper presents a numerical model for the analysis of the soil-structure kinematic interaction of single piles and pile groups embedded in layered soil deposits during seismic actions. A finite element model is considered for the pile group and the soil is assumed to be a Winkler-type medium. The pile-soil-pile interaction and the radiation problem are accounted for by means of elastodynamic Green’s functions. Condensation of the problem permits a consistent and straightforward derivation of both the impedance functions and the foundation input motion which are necessary to perform the inertial soil-structure interaction analyses. The proposed model allows calculating the internal forces induced by soil-pile and pile-to-pile interactions. Comparisons with data available in literature are made to study the convergence and validate the model.

Abstract

The paper presents a numerical model for the analysis of the soil-structure kinematic interaction of single piles and pile groups embedded in layered soil deposits during seismic actions. A finite element model is considered for the pile group and the soil is assumed to be a Winkler-type medium. The pile-soil-pile interaction and the radiation problem are accounted for by means of elastodynamic Green’s functions. Condensation of the problem permits a consistent and straightforward derivation of both the impedance functions and the foundation input motion which are necessary to perform the inertial soil-structure interaction analyses. The proposed model allows calculating the internal forces induced by soil-pile and pile-to-pile interactions. Comparisons with data available in literature are made to study the convergence and validate the model.
