CONNECTED VIBRATION CONTROL STRUCTURE
PROBLEM TO BE SOLVED: To provide a connected vibration control structure that is configured in consideration of the above problems and that can exert a sufficient vibration control effect even when rigidity of a structural member is low.SOLUTION: In a connected vibration control structure 1, an existing building (one structure) 2 and an outer frame (the other structure) 3 are connected together via a vibration control damper (vibration reduction device) 4, and vibrations of the existing building 2 are reduced. The vibration control damper 4 comprises an inertia mass damper (rotational inertia mass mechanism) and an oil damper (vibration attenuation mechanism). A natural frequency determined from the inertia mass damper and rigidity of the outer frame 3 is set to be synchronized with a natural frequency of the existing building 2.
【課題】上述する問題点に鑑みてなされたもので、構造部材の剛性が小さい場合にも十分な制震効果を発揮することができる連結制震構造を提供する。【解決手段】既存建物（一方の構造物）２とアウトフレーム（他方の構造物）３とを制震ダンパ（振動低減装置）４を介して連結し、既存建物２の振動を低減させる連結制震構造１において、制震ダンパ４は、慣性質量ダンパ（回転慣性質量機構）およびオイルダンパ（振動減衰機構）を備え、慣性質量ダンパとアウトフレーム３の剛性とから決定される固有振動数は、既存建物２の固有振動数と同調するように設定されている。【選択図】図１
