Abstract: A simplified approach for the transient dynamic response analysis of embedded multiple rigid foundations is presented. The approach is based on approximate time-domain formulations of the interaction force acting along the side and of motions transmitted from one foundation body to another. All of those formulations are developed within the Winkler's hypothesis. Some numerical examples are given to demonstrate the approach. It is confirmed that the approach is efficient in computation and can accommodate the nonlinear mechanism in a rational manner.
