ROTARY INERTIA MASS DAMPER
To provide a rotary inertia mass damper capable of being easily synchronized with a natural period in design in a case where a natural period after completion of a building is different from the natural period in design.SOLUTION: A rotary inertia mass damper 1 has a ball screw 2, a nut 3 screwed into the ball screw 2, and a rotary weight 4 that is arranged on the outer peripheries of the ball screw 2 and the nut 3 and to which the rotational movement of the nut 3 is transmitted. The rotary weight 4 has a cylindrical weight body 41 surrounding the ball screw 2 and the nut 3, and an additional weight 42 capable of being attached to the outer periphery of the weight body 41 in a detachable manner.SELECTED DRAWING: Figure 2
【課題】建物の竣工後の固有周期が設計時の固有周期と異なる場合に、設計時の固有周期に容易に同調させることができる回転慣性質量ダンパーを提供する。【解決手段】ボールねじ２と、ボールねじ２に螺合するナット３と、ボールねじ２およびナット３の外周に配置され、ナット３の回転運動が伝達される回転錘４と、を有する回転慣性質量ダンパー１において、回転錘４は、ボールねじ２およびナット３を囲繞する円筒状の錘本体４１と、錘本体４１の外周に着脱可能な付加錘４２と、を有することを特徴とする。【選択図】図２
