VIBRATION CONTROL STRUCTURE AND VIBRATION CONTROL BUILDING

To provide a vibration control structure and a vibration control building provided with the same which can absorb vibration energy in both deformation modes of overall bending deformation and layer shearing deformation.SOLUTION: A vibration control building 1 including a vibration control structure arranged in a column and beam frame 4 of a mid-to-high-rise building comprises: diagonal members 6, 46 whose one ends are connected to the column and beam frame; attenuation devices 13, 43 which are arranged in parallel to beam members 3 constituting the column and beam frame and whose one ends are connected to column members 2 constituting the column and beam frame; vertical members 61 whose one ends are connected to the beam members and which are hung and supported; and joint members 31, 51 to which each one end of the diagonal member, the attenuation device, and the vertical member is connected. First vibration control means 10 is constituted of the column member, the diagonal member, the vertical member, and the attenuation device, and a stud 11 is installed between the column members with a space between the stud and the first vibration control means. Inside the column and beam frame, in addition to the column member, the diagonal member, and the attenuation device forming the first vibration control means, second vibration control means 40 constituted of the studs and short span beam members 3S formed of the studs is installed.SELECTED DRAWING: Figure 1 【課題】全体曲げ変形、層せん断変形のいずれの変形モードに対しても振動エネルギーを吸収することができる、制振構造及び、これを備えた制振建物を提供する。【解決手段】中高層建物の柱梁架構４内に設置される制振構造を備えた制振建物１であって、柱梁架構に一方端が接合された斜材６、４６と柱梁架構を構成する梁部材３に並設し柱梁架構を構成する柱部材２に一方端が接合された減衰装置１３、４３と一方端が梁部材に接合され吊り下げ支持された鉛直部材６１と、斜材と減衰装置及び鉛直部材の他方端同士が連結された接合部材３１、５１とを備え、柱部材と斜材、鉛直部材、減衰装置で第１の制振手段１０が構成され、柱部材間には第１の制振手段と隙間を空けて間柱１１が設置され、柱梁架構内には第１の制振手段を形成する柱部材と斜材、減衰装置に加えて間柱と該間柱により形成された短スパン梁部材３Ｓで構成された第２の制振手段４０が設置される。【選択図】図１
