Dynamics of Soil‐Base‐Isolated‐Structure Systems

Abstract

A study of the effects of soil‐structure interaction on the dynamic response of linear base‐isolated structures is presented. The structures are supported at the surface of a homogeneous and viscoelastic half‐space and are excited at the foundation. The conditions under which the interaction effects are of sufficient importance to warrant consideration in design are defined. These conditions appear to be different than corresponding conditions for conventional structures, and in particular, the interaction effects in base‐isolated structures are not as important as those in conventional structures.
