DAMPING STRUCTURE
To provide a damping structure capable of suppressing vibration of an upper story part even when a higher-order mode vibration occurs in a high-rise or super-high-rise structure.SOLUTION: In a damping structure 1 which suppresses higher-order mode vibration which occurs in an upper story part 4 which is an uppermost part of a high-rise or super-high-rise structure 2, a rotary inertia mass damper 51 which is tuned to the higher-order mode vibration is provided at a lower story part 3 below the upper story part 4. The plurality of rotary inertia mass dampers 51 are arranged in the vertical direction and are provided so as to act across a plurality of stories in the lower story part 3.SELECTED DRAWING: Figure 1
【課題】高層や超高層の構造物において高次モードの振動が生じた場合にも上層部の振動を抑えることができる制振構造を提供する。【解決手段】高層または超高層の構造物２の最上部分となる高層部４に生じる高次モードの振動を抑える制振構造１において、高層部４の下側の下層部３に高次モードの振動に同調する回転慣性質量ダンパー５１が設けられている。回転慣性質量ダンパー５１は、上下方向に複数配列され、それぞれ下層部３における複数層に跨って作用するように設けられている。【選択図】図１
