A brief discussion of soil-structure interaction, particularly in terms of its effects on structures subjected to earthquakes, is presented. Factors influencing the degree to which soil-structure interaction modifies the response of structures, when compared to the response of rigid-based structures, are listed. The distinction between inertial and kinematic components of soil-structure interaction is made and the generally beneficial effects of interaction on earthquake structural response is noted. Soil-structures interaction effects are most pronounced in rigid, massive structures founded on compliant soils. Brief mention is made of the uncertainties surrounding the determination of interaction effects on structural response, especially those associated with the effects of nonlinear soil behavior.
