Passive based isolation systems used for the seismic response control of structures appear of be effective for small to medium strength earthquakes. Hybrid base isolation systems, which use an active system together with the passive base isolation system, may be used to control the response of structures subjected to larger ground motions created by larger magnitude earthquakes. A new hybrid base isolation system using passive base isolation pads together with hydraulic type actuators is proposed. The system, placed between the foundation of the building and its superstructure, is used to minimize the forces imposed on the superstructure by the earthquake induced ground motion. The behavior of the hybrid base isolation system is demonstrated with an idealized structural model, and simulations are done for different types of loadings. Time delay in the sensing, processing, and actuation affects the performance of the control system. The affect of the time delay problem on the performance of the control system is studied.
