SEISMIC BASE ISOLATION STRUCTURE WITH VIBRATION CONTROL FUNCTION
PROBLEM TO BE SOLVED: To provide a seismic base isolation structure including vibration control function showing a superior vibration control function at an upper floor of a high rise building.SOLUTION: This invention relates to a seismic base isolation structure 1 with vibration control function comprising a seismic base isolation device 4 arranged between the ground and a structure 3 to support the structure and remove vibration of the structure in a horizontal direction H in respect to the ground; vibration control means for controlling vibration of the structure in a horizontal direction H in respect to the ground; and a supporting block 6 fixed to the ground. The vibration control means comprises a plurality of mass dampers 5 constituted by a mass body 5a contacted with the upper surface of the supporting block at its lower surface and movably supported under a low friction in a horizontal direction on the supporting block; resilient bodies 5b each of which is connected at one end to the structure and at the other end to the mass body in such a way that the mass body is vibrated in a horizontal direction through resilient extension or shrinkage in response to a vibration of the structure in a horizontal direction in respect to the supporting block; and vibration energy absorbing means 5c each of which is connected at one end to the structure and at the other end to the mass body so as to absorb vibration energy in response to the vibration of the mass body in a horizontal direction in respect to the supporting block.SELECTED DRAWING: Figure 1
【課題】高層建築物の上層階における制振機能に優れる制振機能付き免震構造物を提供する。【解決手段】地盤と構造物３との間に配置され、構造物を支持すると共に、構造物の地盤に対する水平方向Ｈの振動を免震する免震装置４と、構造物の地盤に対する水平方向の振動を制振する制振手段と、地盤に固定された支持台６とを備える制振機能付き免震構造物１であって、制振手段は、下面で支持台の上面に接触して支持台に水平方向に低摩擦で移動自在に支持される質量体５ａと、構造物の支持台に対する水平方向の振動に応答して質量体を弾性的な伸縮により水平方向に振動させるように、一端で構造物に他端で質量体に各々連結された弾性体５ｂと、質量体の支持台に対する水平方向の振動に応じてその振動エネルギを吸収するように、一端で構造物に他端で質量体に各々連結された振動エネルギ吸収手段５ｃで構成される質量ダンパ５を複数備える制振機能付き免震構造物。【選択図】図１
