Abstract

Earthquakes are disruptions to the movement of the ground resulting from the abrupt release of strain energy in the Earth’s crust. The release of energy causes seismic waves, which cause vibrations in civil structures and potentially result in damage. Protecting structures against these unpredictable occurrences, this study employs a novel magnetorheological elastomer (MRE) mixed-base isolation system, integrated with a semi-active fuzzy logic control, to effectively mitigate vibrations in a 5-story building. The design of the isolator, combined with the adaptive control method, dramatically decreases the maximum displacement by 45% and the maximum acceleration by 13% when subjected to a scaled El Centro 1940 seismic wave. This balanced control illustrates the intriguing potential of the proposed system in improving the resilience of buildings and ensuring the comfort of occupants in the face of vibrations caused by earth-quakes.
