Abstract: Transient and steady-state responses of a one-story building model with an embedded foundation subjected to plane horizontally-polarized shear waves are derived and analyzed. Soil-structure interaction effects are especially emphasized and a comparison of the rigorous results is made with the results for an analogous simplified model for which the interaction effects are neglected. It is shown that a conventional mass-dashpot-spring model fails to describe the actual complicated interaction effects associated with the scattering of waves around the foundation.
