VIBRATION RESTRAINT DEVICE OF STRUCTURE
PROBLEM TO BE SOLVED: To provide a vibration restraint device capable of sufficiently restraining vibration of a structure, by properly interlocking two dampers when the structure vibrates.SOLUTION: One end part in the horizontal direction of a transmission member higher in rigidity than a column of a structure erected on a support body, is integrally provided on a column, and a first cylinder filled with a working fluid is connected to the support body, and a first piston for partitioning the first cylinder-inside into first and second fluid chambers, is connected to the other end in the horizontal direction of a lower end part of the transmission member. A second cylinder filled with the working fluid is connected to a lower part of the structure, and a second piston for partitioning the second cylinder-inside into third and fourth fluid chambers is connected to the support body. When the structure is displaced to one side by vibration of a primary mode, force in the direction for respectively moving the first piston to the first fluid chamber side and the second piston to the third fluid chamber side acts, and the first and third fluid chambers communicate via a first communication passage and the second and fourth fluid chambers communicate via a second communication passage, respectively.SELECTED DRAWING: Figure 2
【課題】構造物の振動時、２つのダンパを適切に連動させられることにより、構造物の振動を十分に抑制できる振動抑制装置を提供する。【解決手段】支持体に立設された構造物の柱よりも剛性が高い伝達部材の水平方向の一端部が、柱に一体に設けられ、作動流体が充填された第１シリンダが、支持体に連結され、第１シリンダ内を第１及び第２流体室に区画する第１ピストンが、伝達部材の下端部の水平方向の他端部に連結されている。作動流体が充填された第２シリンダが、構造物の下部に連結され、第２シリンダ内を第３及び第４流体室に区画する第２ピストンが、支持体に連結されている。構造物が１次モードの振動により一方の側に変位したときに、第１ピストンを第１流体室側に、第２ピストンを第３流体室側に、それぞれ移動させる方向の力が作用し、第１及び第３流体室が第１連通路を介して、第２及び第４流体室が第２連通路を介して、それぞれ連通している。【選択図】図２
