Abstract

A new discrete model for the study of dynamic interaction phenomena between adjacent, rigid foundations on a homogeneous, linear elastic half-space is presented. Each dynamic degree of freedom of the foundations consists of a mass connected to a rigid support through frequency independent springs and dashpots. The interaction between the foundations is achieved by imposing spring and damping couplings developed in this work. The time lagging effects of coupled dynamic input due to wave propagation is also considered through a proposed modified vector approach. 1 Introduction At the inception of SSI analysis, the engineering profession had very little theoretical and observational data for developing reliable methods of predicting dynamic foundatio
