BASE-ISOLATED BUILDING PROVIDED WITH FAILSAFE MECHANISM
To provide a base-isolated building 1 provided with a failsafe mechanism 30 mitigating impact force upon collision of an upper structure 10 to a protection wall 23 without impeding clearance uc between the upper structure 10 and the protection wall 23 for the base-isolated building 1.SOLUTION: The base-isolated building 1 provided with the failsafe mechanism 30 is provided with a base isolation mechanism 22. The base-isolated building 1 is provided with the failsafe mechanism 30 in the upper structure 10 upper than the base isolation mechanism 22. The failsafe mechanism 30 includes a synchronous type mass damper 32 exhibiting a synchronous effect on at least one of secondary or higher unique oscillation modes of the base-isolated building 1.SELECTED DRAWING: Figure 1
【課題】本発明は、免震建物１における上部構造体１０と擁壁２３とのクリアランスｕｃを阻害することなく、上部構造体１０が擁壁２３に衝突した時の衝撃力を緩和するフェールセーフ機構３０を備える免震建物１を提供する。【解決手段】フェールセーフ機構３０を備える免震建物１は、免震機構２２を備えた免震建物１である。免震建物１は、免震機構２２よりも上の上部構造体１０にフェールセーフ機構３０を備える。フェールセーフ機構３０は、免震建物１の２次以上の固有振動モードの少なくとも１つに対して同調効果を発揮する同調型マスダンパー３２を含む。【選択図】図１
