VIBRATION REDUCTION MECHANISM OF FLOOR PART
To provide a floor vibration reduction mechanism which can economically install a rotary inertial mass damper regardless of a span of a cantilever.SOLUTION: A support beam 61 (support portion) which supports a base end portion 22 of a cantilever beam 2, a small beam 7 (end supported beam) which is supported by the support beam 61 at one end and is joined to the cantilever beam 2 via the support beam 61, and a rotary inertial mass damper 8 provided between the floor slab 3 and the support beam 61 and connected to each of the floor slab 3 and the support beam 61 are provided. Vibration of the cantilever 2 is transmitted to the small beam 7 via the support beam 61, and the cantilever 2 and the beam 7 can vibrate synchronously with the support beam 61 as a fulcrum, and the floor slab 3 and the support beam 61 can vibrate relative to each other. The rotary inertial mass damper 8 is configured to operate by the relative vibration between the slab 3 and the support beam 61, and the rotary inertial mass damper 8 is connected at a position on the support beam 61 side of a tip portion 21 of the cantilever 2 in the floor slab 3, and at a position which does not overlap the cantilever 2 in the vertical direction.SELECTED DRAWING: Figure 1
【課題】片持ち梁のスパンに関わらず、経済的に回転慣性質量ダンパを設置することができる床部の振動低減機構を提供する。【解決手段】片持ち梁２の基端部２２を支持する支持梁６１（支持部）と、一端が支持梁６１に支持され、支持梁６１を介して片持ち梁２と接合される小梁７（両端支持梁）と、床スラブ３と支持梁６１との間に設けられ床スラブ３および支持梁６１それぞれと接続される回転慣性質量ダンパ８と、が設けられ、片持ち梁２の振動が支持梁６１を介して小梁７に伝達され、片持ち梁２と小梁７とが支持梁６１を支点として同期して振動可能とされ、床スラブ３と支持梁６１とは、相対振動可能で、床スラブ３と支持梁６１との相対振動により回転慣性質量ダンパ８が作動するように構成され、回転慣性質量ダンパ８は、床スラブ３における片持ち梁２の先端部２１よりも支持梁６１側の位置で、かつ片持ち梁２と鉛直方向に重ならない位置に接続されている。【選択図】図１
