✦ Synopsis

A simple model for the seismic response of a one-storey structure subjected to active control in the presence of soilstructure interaction e ects is presented. The approach is based on the successive use of equivalent 1-DOF oscillators which account for the e ects 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 e ects 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 e ects. A simple procedure to include the interaction e ects on the control gains is also presented. ? 1998

Methods that combine frequency and time domain techniques offer an attractive alternative for solving Soil-Structureinteraction problems where the structure exhibits non-linear behaviour. In the hybrid-frequency-time-domain procedure a reference linear system is solved in the frequency domain and th
