摘要：
A simple model for the seismic response of a one-storey structure subjected to active control in the presence of soil-structure interaction effects is presented. The approach is based on the successive use of equivalent 1-DOF oscillators which account for the effects of control and soil-structure interaction. Simple expressions for these oscillators based on exact analytical solutions of the control equations and approximate solutions of the interaction equations are presented. The study includes an evaluation of the effects of soil-structure interaction on the seismic response of actively controlled structures in which the control gains have been determined with and without inclusion of soil-structure interaction effects. A simple procedure to include the interaction effects on the control gains is also presented.
