BRACE DAMPER
PROBLEM TO BE SOLVED: To provide a brace damper capable of being thin and light while securing a desired damper bearing force and also be easily manufactured and reduced in cost.SOLUTION: A brace damper includes: a core material 1; a buckling restraining material 2 for preventing the core material from buckling; and an insulation material 3 arranged between the core material 1 and the buckling restraining material 2. The core material 1 is extended along an axis line O1 direction and includes: a plasticized part 4 absorbing oscillation energy by plastic deformation when oscillation energy is applied; and a pair of junctions 5, 6 respectively provided on both end sides of the axis line O1 direction. The buckling restraining material 2 is laminated so as to sandwich the core material 1 and the insulation material 3, and includes: a pair of antiplane restraining materials 14 restraining the out-of-plane deformation of the plasticized part 4 of the core material 1; and a pair of in-plane restraining materials 15 installed by connecting to the pair of the antiplane restraining materials 14 and also arranged so as to encircle the core material 1 together with the antiplane restraining materials 14 to restrain in-plane deformation of the plasticized part 4 of the core material 1.
【課題】所望のダンパー耐力を確保しつつ、細く、軽量にすることができ、且つ製作が容易で低コストにすることが可能なブレースダンパーを提供する。【解決手段】芯材１と、芯材１の座屈を防止するための座屈拘束材２と、芯材１と座屈拘束材２の間に配設される絶縁材３とを備える。また、芯材１は、軸線Ｏ１方向に沿って延設され、振動エネルギーが作用した際に塑性変形してこの振動エネルギーを吸収する塑性化部４と、軸線Ｏ１方向両端部側にそれぞれ設けられ、建物の架構に接続するための一対の接合部５、６とを備える。座屈拘束材２は、芯材１及び絶縁材３を挟み込むように積層配置され、芯材１の塑性化部４の面外変形を拘束する一対の面外拘束材１４と、一対の面外拘束材１４に連結して架設され、且つ一対の面外拘束材１４とともに芯材１を囲繞するように配設され、芯材１の塑性化部４の面内変形を拘束する一対の面内拘束材１５とを備える。【選択図】図１
