Research on Numerical Simulation of Smart Base Isolation System with MR Damper(II)

Abstract:

Rubber bearing base-isolation is well-developed vibration reduction technique, and is applied in practical engineering broadly. But displacement of vibration isolating layer is large, so lead plug rubber bearing is used. It is passive control device; therefore its optimal central extent is narrow. That is isolating layer is optical in several defined kind and magnitude of earthquake waves, in the way controlled displacement and acceleration of superstructure is ideal. Magnetorheological damper has good smart performances- broad controlled band, fast response and demand a little energy. In this paper smart base isolation system, which is combined with rubber bearing and MR damper, is applied to structural vibration control, and have numerical simulation of structure employing LRB isolation and smart isolation in different kind and magnitude of earthquake waves. The result indicates smart base-isolation with MR damper can supply optimal control to these different earthquake waves, so is a good supplement and perfection for former isolation technique.
