VIBRATION DAMPING STRUCTURE
To suppress vibrations of structures with different amplitudes and frequencies using a single vibration damping structure.SOLUTION: A vibration damping structure includes: a plurality of first seismic isolation bearings which are arranged on an upper portion of a structure and each of which is either one of an elastic bearing or an elasto-plastic bearing having higher rigidity than the elastic bearing; an intermediate member which is placed on the plurality of first seismic isolation bearings; a plurality of second seismic isolation bearings which are placed on the intermediate member and each of which is the other of the elastic bearing or the elasto-plastic bearing; a mass body which is placed on the plurality of second seismic isolation bearings; and an attenuation damper which is arranged on a layer on which the first seismic isolation bearing that is the elastic bearing is provided or on a layer on which the second seismic isolation bearing that is the elasto-plastic bearing is provided, with one end attached to the intermediate member and the other end attached to the upper portion or the mass body of the structure.SELECTED DRAWING: Figure 1
【課題】振幅及び振動数が異なる構造物の振動を単一の制振構造で抑制することである。【解決手段】制振構造は、構造物の上部に配置され、弾性支承及び弾性支承と比して高剛性である弾塑性支承のどちらか一方とされた複数の第一免震支承と、複数の第一免震支承に載せられた中間部材と、中間部材に載せられると共に弾性支承及び弾塑性支承のどちらか他方とされた複数の第二免震支承と、複数の第二免震支承に載せられた質量体と、弾性支承とされた第一免震支承が設けられた層、又は弾性支承とされた第二免震支承が設けられた層に配置され、一端が中間部材に取り付けられ、他端が構造物の上部又は質量体に取り付けられた減衰ダンパーと、を備える。【選択図】図１
