Abstract
The dynamic impedance of a pile group must be determined to perform a dynamic response analysis of the structure it supports. This problem has attracted continued research interest, but most research to date has been on linear soil media. When the excitation level becomes large during an earthquake or a machine type excitation, stress concentration occurs in the soil surrounding the pile, causing the soil to behave nonlinearly. Calculation of pile group impedance necessitates analysis of pile-soil-pile interaction. Any soil nonlinearity around the piles must be taken into account in this analysis. However, the effect of nonlinearity on dynamic impedance has not been examined adequately. This paper describes an analysis method, and presents numerical results for the nonlinear dynamic impedance of a pile group and for the distribution of forces on the pile caps.
