PROBLEM TO BE SOLVED: To provide a base-isolated structure which prevents a thin rubber plate in a base isolation device from yielding when a giant earthquake occurs. SOLUTION: According to the base-isolated structure 1, the base isolation device 4 is interposed between a steel pipe pile 2 and a cut-off foundation 3, and specifically the base isolation device 4 is set on an encasing concrete section 10 formed around a pile head 9. The encasing concrete section 10 is formed such that concrete 7 filled in a steel pipe 6 overflows to cover the pile head 9 protruding from the ground 8. Then a tension member 5 is penetrated from the steel pipe pile 2 via the base isolation device 4 to the foundation 3. COPYRIGHT: (C)2007,JPO&INPIT
