Abstract
An active control strategy for base-isolated structures is proposed in this work. The key idea comes from the observation that passive base isolation systems are hysteretic. Thus, an hysteresis based vibration control is designed in a way that the control force is smooth and limited by a prescribed bound. A model of a three-story building is used to study and compare the efficacy of a passive pure friction damper alone, with the addition of the proposed active control. We introduce a rate limite...
