BASE ISOLATION STRUCTURE FOR BUILDING
To provide a base isolation structure of a building capable of effectively suppressing deformation accompanying vibration of an upper structure and a lower structure without requiring a special base isolation rubber support and even though a commercially available base isolation rubber support can be used.SOLUTION: In a base isolation structure of a building, a multi-story building 1 is divided into an upper structure 2 and a lower structure 3, and a base isolation support 5 is installed on an intermediate floor 4 between the upper structure 2 and the lower structure 3 so that the upper structure 2 functions as a weight of a TMD, the base isolation bearing 5 is a base isolation rubber bearing 5 and has 2.0 - 4.0 times higher horizontal rigidity than the normal horizontal rigidity corresponding to the axial force to be normally borne.SELECTED DRAWING: Figure 1
【課題】特殊な免震ゴム支承を必要とせず、市販の免震ゴム支承を使用し得るのもかかわらず、上部構造物と下部構造物の震動に伴う変形を効果的に抑制することが可能な建物の免震構造の提供。【解決手段】多層階の建物１が、上部構造物２と下部構造物３とに区分けされ、上部構造物２がＴＭＤの錘として機能するように、上部構造物２と下部構造物３との間の中間階４に免震支承５が設置される建物の免震構造であって、免震支承５が、免震ゴム支承５であって、通常負担すべき軸力に見合う通常の水平剛性に対して、２．０〜４．０倍の高い水平剛性を有する。【選択図】図１
