BUCKLING RESTRAINT BRACE, AND FRAMEWORK INCLUDING THE BUCKLING RESTRAINT BRACE
To provide a buckling restraint brace capable of high yield strength while maintaining a binding force even when deformed, and a framework including the buckling restraint brace.SOLUTION: A disclosed buckling restraint brace 1 is a buckling restraint brace 1 that includes a cross-section steel core 3 and a wooden buckling restraint 5 arranged enclosing the core 3. The core 3 has elastic parts 7 that elastically deform on both ends in the longitudinal direction and has a plasticized section 9 consisting of a cross-section in which the width of the horizontal section is greater than that of the vertical section in the part sandwiched between the elastic parts 7. The buckling restraint 5 consists of a pair of members arranged and joined so as to sandwich the core 3 from the vertical direction or the width direction, and has a groove 15 corresponding to the shape of core 3 on the joint surface of each member. With the core 3 placed in the groove 15, a gap between the horizontal part of the core 3 and buckling restraint 5 is set to be smaller than the gap in the vertical direction between the buckling restraint member 5 and the vertical portion of the core member 3.SELECTED DRAWING: Figure 1
【課題】高い耐力が期待できると共に変形時においても拘束力を維持できる座屈拘束ブレース及び該座屈拘束ブレースを備えた架構を提供する。【解決手段】本発明に係る座屈拘束ブレース１は、鋼製で十字断面の芯材３と、芯材３の周囲を覆うように配された木製の座屈拘束材５とを備えた座屈拘束ブレース１であって、芯材３は、長手方向の両端部に弾性変形する弾性部７を有し、弾性部７に挟まれた部分に水平部分の幅が鉛直部分のせいよりも大きい十字断面からなる塑性化部９を有し、座屈拘束材５は、芯材３をせい方向または幅方向から挟むように配されて接合された一対の部材からなり、各部材の接合面に芯材３の形状に対応した溝部１５を有し、芯材３を溝部１５内に配設した状態において、芯材３の水平部分における座屈拘束材５とのせい方向の隙間が、芯材３の鉛直部分における前記座屈拘束材５とのせい方向の隙間よりも小さく設定されている。【選択図】 図１
