In this report, we suggest the new intelligent fluid applying MR fluid, and new base isolation system using that new intelligent fluid. At first, new intelligent fluid suggested in this report as FFF (Flexible Fixable Fluid) consist of some magnetic fluid and special particles. The most remarkable characteristic of the FFF is that this fluid gives stable and optional yield stress by gathering the properties of containing materials. By the way, in the region where the earthquake often happens, buildings and industrial equipments must be provided for earthquakes. Now, fuse property is examined as the most anticipative idea for base isolation system. That is, base isolation system holds structures by stable holding force at usual condition or slight earthquake. On the other hand, at a severe earthquake, it releases holding force and insulates transfer of force by earthquake at the base of structure by yielding relative displacement between ground and base of structure. According to such idea, we developed new base isolation system utilizing characteristic of FFF.
