さくすると質量部材の重量を大きくする必要がある。[Detailed Description of the Invention] [Industrial Application Field] The invention prevents high-rise buildings, tower-like buildings, or buildings that are thin compared to their height from vibrating greatly due to earthquakes or strong winds. This relates to a vibration damping device for a building that is placed on the top of a building.
There is a proposal shown in Publication No. 74. This publication states that the conventional allocation device installed at the Chiba Port Tower is mechanically constructed and is complex and expensive. Therefore, the mass member disposed on the upper part is supported by a laminated rubber layer, and the elastic restoring force is adjusted by a helical spring. If the amplitude becomes large, it becomes unstable, and if the amplitude is made small, it is necessary to increase the weight of the mass member.
