造物の骨組７に固定した振動抑制装置が知られている。Conventionally, as a vibration suppressing device for a building, as shown in FIGS. 9 to 12, a plurality of steel plates 11 fixed to one end of a steel bracing member 10 and a steel mounting member 12 are fixed. And a plurality of steel plates 13 arranged alternately, and the viscoelastic material layer 4 is interposed between the adjacent steel plates 11 and 13, and the other ends of the steel bracing material 10 are fixed. There is known a vibration suppressing device in which the steel mounting member 12 is fixed to a frame 7 of a building.

じる。In the case of the conventional vibration suppression device for a building, since the total area of the viscoelastic material layer 4 is small, there is a disadvantage that the vibration energy absorption capability of one vibration suppression device is small. In order to increase the vibration energy absorption capacity,
When the number of laminations of the layer 3 and the viscoelastic material layer 4 is increased, the cross section of the lamination portion becomes large, which causes a disadvantage that the wall thickness for surrounding the vibration suppressing device becomes thick in the plan of the building.
