Smart Base Isolation Control Adopted Semi-Active Fuzzy Strategy for Seismic Response of Structure
According to the disadvantages of the effects that base isolation was limited to high frequency components of seismic wave, smart base isolation system consisting of rolling isolation bearing and magnetorheological damper was applied to structural vibration control. Based on magnetorheological damper employing a Sigmoid model, a semi-acive fuzzy control strategy suitable for smart base isolation was presented. Simulation analysis was carried out to a two-story steel frame structure employing smart base isolation in the action of different kinds and magnitudes of earthquake wave. The results show that smart base isolation system is reliable and effective, and seismic response can be controlled effectively by semi-active fuzzy strategy.
