A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity of the soil, pile separation, and individual pile response. The study is implemented through Monte Carlo simulations, for maximum and minimum expected degrees of variability in the field. It is concluded that for certain field conditions, random variations can significantly affect the group response by reducing constructive and destructive wave interference. Further studies are suggested as part of the development of an engineering method for dynamic pile group evaluations.
