Abstract

A direct time domain BEM formulation of the general inertial SSI problem is presented. The dynamic response of a rigid massive foundation resting on the surface of a linear elastic, homogeneous, isotropic half-space and subjected to externally applied forces is computed for illustration purposes. Results for rectangular and circular foundations are presented assuming, i) complete bond with the half-space, and ii) relaxed boundary conditions. Comparison studies with frequency domain or simplified time domain analyses confirm the results of this study.
