heal.abstract	Seismic isolation tends to be established as one of the main methods to reduce seismic hazard in bridge structures. However, the significance of the subsoil in affecting the overall response of the bridge-isolator-soil system remains an issue that deserves the attention of structural engineers. In the present study the coupled effects of base isolation and soil-structure interaction on the seismic response of bridge piers are studied. Simple analytical models that incorporate the most important features of the coupled system are used. Appropriate expressions are applied to simulate two basic subsoil conditions: homogenous halfspace and soil-stratum underlined by bedrock at shallow depth. A number of pertinent parameters of the bridge-isolators-soil system are included in an extensive parametric study and the cases in which soil-structure interaction should be incorporated in design are identified. The results can be applied to select the appropriate isolation system parameters, at a preliminary design level, and enhance system safety and reduction of construction cost. © 2007 Civil-Comp Press.	en
