Magnetorheological elastomer (MRE) base isolator is a semi-active control device which has currently obtained increasing attention in the field of vibration control of civil structures.
Therefore, an accurate and robust model is essential to make full use of these unique features for its engineering applications.
Introduction Magnetorheological elastomer (MRE) base isolators have been developed and regarded as one of the most ideal devices for implementation of semi-active control in base isolation system of civil structures against various hazard external excitations such as winds and earthquakes.
However, the nonlinear force-displacement response of this device is considered as the main challenge for its control application in civil structures.
