Abstract

The formulation of the Substructure Deletion Method (SDM) is extended to describe the dynamic response of two or more embedded foundations interacting through the soil. The methodology is based on surface Green's functions for layered half-spaces and a Boundary Element representation of the bounded excavated domain. Stationary dynamic behavior and plane strain conditions are assumed throughout the article. Numerical results are validated by comparison with a Boundary Element-only implementation. Reported results include frequency dependent compliance functions of two foundations for various frequencies, foundation distances and embedment ratios. 1 Int
