VIBRATION SUPPRESSION DEVICE FOR STRUCTURE
To provide a vibration suppression device for structures that can exert a large rotational inertia mass effect even when a support member is short, and that can provide sufficient vibration suppression effect while significantly reducing a buckling stoppage of the support member.SOLUTION: A vibration suppression device for a structure of the present invention comprises a horizontal force supporting element (brace 5) which is installed between an outer column (first outer column PE1) arranged at one end of a structure S and an adjacent inner column EI and supports a horizontal force acting on the structure S at a larger burden ratio, a support member 2 arranged in a middle to a lower part of the structure S in a vertical direction and connected to the outer column at an its upper end and a mass damper 3 which is connected between a foundation F and a lower end of the support member 2, constitutes an additional vibration system A with the support member 2, has a rotating mass 16, and exerts a rotational inertia mass effect and a viscous damping effect by converting a vertical displacement of the structure S transmitted through the support member 2 into a rotational motion of the rotating mass 16 during vibration of the structure S.SELECTED DRAWING: Figure 1
【課題】支持部材が短い場合においても、大きな回転慣性質量効果を発揮させ、支持部材の座屈止めを大幅に削減しながら、十分な振動抑制効果が得られる構造物の制振装置を提供する。【解決手段】本発明の構造物の制振装置は、構造物Ｓの一端部に配置された外柱（第１外柱ＰＥ１）と隣接する内柱ＥＩとの間に設置され、構造物Ｓに作用する水平力をより大きな負担割合で支持する水平力支持要素（ブレース５）と、構造物Ｓの上下方向の中間部から下側に配置され、上端部が外柱に接続された支持部材２と、基礎Ｆと支持部材２の下端部との間に接続され、支持部材２とともに付加振動系Ａを構成するとともに、回転マス１６を有し、構造物Ｓの振動時に、支持部材２を介して伝達される構造物Ｓの鉛直変位を回転マス１６の回転運動に変換することによって、回転慣性質量効果及び粘性減衰効果を発揮するマスダンパ３と、を備える。【選択図】図１
