PROBLEM TO BE SOLVED: To provide a seismically isolated structure in which an upper structure is not separated from a foundation structure even if it is subject to a strong tensile force due to earthquake.SOLUTION: A seismically isolated structure has a seismic isolator 3 between a foundation structure 1 and an upper structure 2. In the seismically isolated structure, a tensile material 4 is placed between the foundation structure 1 and a footing 13 that is installed on a column base part 11a of the upper structure 2. The tensile material 4 is installed in U-turn shape by being inserted into sheaths 7,16 buried into the foundation structure 1 and both end parts of the tensile material 4 are respectively anchored and fixed to an anchorage zone 18 provided on the footing 13 by using anchorage devices 26.SELECTED DRAWING: Figure 1
【課題】地震による大きな引張力を受けても上部構造が基礎構造から分離しないようにした免震構造物を提供する。【解決手段】基礎構造１と上部構造２との間に免震装置３が設置された免震構造物であって、基礎構造１と上部構造２の柱脚部１１ａに設けられたフーチング１３とに渡って引張材４が設けられ、引張材４は、基礎構造１に埋設されたシース７、１６に挿通してＵターン状に配設され、引張材４の両端部がそれぞれフーチング１３に設けられた定着部１８に定着具２６を用いて定着固定された構成とする。【選択図】図１
