SEISMIC ISOLATION STRUCTURE AND SEISMIC ISOLATION REPAIR METHOD OF EXISTING BUILDING
PROBLEM TO BE SOLVED: To provide a seismic isolation structure and a seismic isolation repair method of an existing building, which can maintain originally designed seismic isolation clearance, alleviate collision between an upper structure and a retaining wall even when horizontal displacement equal to or more than a base isolation clearance occurs on the upper structure, and absorb energy.SOLUTION: In a seismic isolation structure, a retaining wall 5 is constructed around a seismic isolation building in which a seismic isolation layer 4 is formed between a foundation 1 and a building 2. A concavity 10 is formed on the retaining wall 5 or a periphery 8 of the seismic isolation building opposite to the retaining wall 5. An attenuation material 13 is set in the concavity 10.SELECTED DRAWING: Figure 1
【課題】設計当初の免震クリアランスを維持した上で、上部構造に免震クリアランス以上の水平変位が生じた場合にも、上部構造と擁壁との衝突を緩和し、かつエネルギー吸収も行うことができる免震構造および既存建物の免震改修方法を提供する。【解決手段】基礎１と建物２との間に免震層４が形成された免震建物の周囲に擁壁５が構築された免震構造において、擁壁５または擁壁５と対向する免震建物の外周部８に凹部１０を形成し、この凹部１０に減衰材１３を設置した。【選択図】図１
