STRUCTURE COMBINING BASE ISOLATION WITH VIBRATION CONTROL
PROBLEM TO BE SOLVED: To suppress deformation of a high-rise part and amplification of vibrations in a structure combining base isolation with vibration control, in which the high-rise part is constructed on a low-rise part supported in a base-isolated state.SOLUTION: A bottom floor 70 of a high-rise part 50 is configured to be susceptible to deformation because of low rigidity. Thus, the bottom floor 70 during earthquakes serves as a vibration control floor to bring about a long period and centralized vibration control (centralized deformation), and the deformation of the high-rise part 50 and amplification of vibrations are suppressed. Consequently, the shock (acceleration) of the earthquake in the high-rise part 50, particularly, near a top floor 54 is reduced.SELECTED DRAWING: Figure 1
【課題】免震支持された低層部の上に高層部が構築された免制振併用構造物における高層部の変形及び振動の増幅を抑制する。【解決手段】高層部５０の最下階７０の剛性が低く変形し易くしている。よって、地震時の最下階７０が制振階として、長周期化及び集中制振（集中変形）し、高層部５０の変形及び振動の増幅が抑制される。よって、高層部５０、特に最上階５４の近傍の地震時の揺れ（加速度）が低減する。【選択図】図１
