REINFORCEMENT METHOD OF EXISTING BASE-ISOLATED BUILDING
PROBLEM TO BE SOLVED: To provide a reinforcement method of an existing base-isolated building capable of securing both base isolation performance against a middle or small earthquake and an earthquake at an earthquake motion level of the original design and safety against a greater earthquake than was assumed in the original design.SOLUTION: In a base isolation layer 3, a displacement-changeover-type passive damper 10 that switches from a low attenuation mode to a high attenuation mode at a preset displacement is installed.SELECTED DRAWING: Figure 1
【課題】中小地震や設計当初の地震動レベルの地震に対する免震性能の確保と、設計当初の想定を超える巨大地震に対する安全性の確保を両立させることができる既存免震建物の補強方法を提供する。【解決手段】免震層３に、予め設定した変位で低減衰モードから高減衰モードに切り替わる変位切替型のパッシブダンパー１０を設置する。【選択図】図１
