VIBRATION-PROOF STRUCTURE OF BUILDING
PROBLEM TO BE SOLVED: To provide a vibration-proof structure capable of installing both TMD for earthquake and TMD for wind even if its space is narrow and capable of effectively restricting oscillation of a building caused by wind and earthquake.SOLUTION: TMD 11 for earthquake operated in response to oscillation of earthquake is installed at the upper-most part 10a of a building 10, and TMD 12 for wind operated in response to oscillation of wind is installed on the TMD for earthquake. The TMD 11 for earthquake is provided with first fixing means 13 for restricting operation against oscillation equal to or less than a first threshold set to a scale of oscillation at the earthquake and releasing the restriction against oscillation exceeding the aforesaid first threshold. The TMD 12 for wind is provided with second fixing means 14 for restricting operation against oscillation exceeding a second threshold set to a scale of oscillation at the earthquake and operating the TMD 12 for wind against oscillation equal to or less than the aforesaid second threshold without performing the aforesaid restriction.SELECTED DRAWING: Figure 1
【課題】狭いスペースであっても地震用ＴＭＤと風用ＴＭＤとを設置することができ、かつ効果的に風および地震に起因する建物の揺れを抑制することができる建物の制振構造を提供する。【解決手段】建物１０の最上部１０ａに地震時の揺れに対して作動する地震用ＴＭＤ１１を設置し、その上に風の揺れに対して作動する風用ＴＭＤ１２を設置し、地震用ＴＭＤ１１に、地震時における揺れの大きさに設定された第１の閾値以下の揺れに対して作動を抑制し、かつ上記第１の閾値を超えた揺れに対して上記抑制を解除する第１の固定手段１３を設け、風用ＴＭＤ１２に、地震時における揺れの大きさに設定された第２の閾値を超えた揺れに対して作動を抑制し、かつ上記第２の閾値以下の揺れに対して上記抑制を行うことなく風用ＴＭＤ１２を作動させる第２の固定手段１４を設けた。【選択図】図１
