A parametric study is presented of dynamic pile-group effects for an idealized soil-pile-structure system consisting of a lumped mass model of a superstructure and elastic piles fully embedded in a homogenous, linearly elastic soil layer. The results are used to develop an approximate method, based upon a beam-on-Winkler foundation model, that can be used for dynamic response analyses of pile-groups in layered elastic soils. The approximate pile-group method is evaluated by comparing computed and observed seismic response data of a building supported by a group of piles. The comparison shows that the dynamic stiffness and damping characteristics of a pile group can be evaluated correctly using the procedure. The pile method was found to provide a rational tool to quantify and evaluate pile-group effects for the seismic response of complex pile-supported structures.
