| Abstract: | According to the disadvantages of the effects that base isolation is limited to high frequency components of seismic wave,smart base isolation system consisting of rolling isolation bearing and magnetorheological(MR) damper is applied to structural vibration control.Based on magnetorheological damper employing a Sigmoid model,a fuzzy semi-acive control strategy suitable for smart base isolation is presented.Simulation analysis is carried out to a two-story steel frame structure employing smart base isolatio... |
