PROBLEM TO BE SOLVED: To provide a base isolated building which can exert high base isolation effect not only on a large earthquake but also on a medium- or small-scale earthquake and minute vibration, and is proof against torsion at the time of exerting base isolation action. SOLUTION: The base isolated building 1 is comprised of a base isolation mechanism 4 interposed between a structure 3 and a foundation 2 of the same. The base isolation mechanism 4 is formed of laminated rubber-bearing base isolation devices 4a, viscous dampers 4b, and oil dampers 4c. The oil dampers 4c are arranged along an X direction and a Y direction in a foundation plane, respectively. COPYRIGHT: (C)2008,JPO&INPIT
