CONSTRUCTION VIBRATION SUPPRESSION STRUCTURE
To provide a construction vibration suppression structure capable of reducing the number of vibration suppression dampers while reducing horizontal two-way vibrations with different natural periods.SOLUTION: The construction vibration suppression structure includes: a construction 10; a mass 30 that is placed above the construction 10 and moves in a first horizontal direction X and a second horizontal direction Y with respect to the construction 10; and a vibration suppression damper 50 that is connected to the construction 10 and the mass 30, and with the expansion and contraction direction as the vertical direction, expands and contracts due to the tilt in the first horizontal direction X and the second horizontal direction, in which the expansion amount of the mass 30 with respect to the unit movement amount in the first horizontal direction X is different from the expansion amount of the mass 30 with respect to the unit movement amount in the second horizontal direction.SELECTED DRAWING: Figure 1
【課題】固有周期が異なる水平二方向の振動を低減しつつ、制振ダンパの数を低減する構造物の制振構造を提供する。【解決手段】構造物の制振構造は、構造物１０と、構造物１０の上方に配置され、構造物１０に対して互いに交差する第一水平方向Ｘ及び第二水平方向Ｙに移動するマス３０と、構造物１０とマス３０とに連結され、伸縮方向を上下方向として第一水平方向Ｘ及び第二水平方向の傾倒に伴って伸縮し、マス３０の第一水平方向Ｘの単位移動量に対する伸び量と、マス３０の第二水平方向の単位移動量に対する伸び量とが異なる制振ダンパ５０と、を備える。【選択図】図１
