BUCKLING RESTRAINT BRACE, FRAMEWORK INCLUDING THE BUCKLING RESTRAINT BRACE
To provide a buckling restraint brace capable of maintaining a binding force even when being deformed while preventing the core from breaking the wooden buckling restraint when deformed, and a framework including the buckling restraint brace.SOLUTION: A disclosed a buckling restraint brace 1 is a buckling restraint brace 1 that includes: a steel core 3; a wooden buckling restraint 5 arranged to enclose the circumference of the core 3; and a penetration prevention plate 6 that is interposed between the buckling restraint material 5 and the core 3 to prevent the core 3 from penetrating the buckling restraint 5. The core 3 consists of a sheet steel or an open section member made by combining multiple steel plates. The buckling restraint 5 consists of a pair of members arranged and joined so as to sandwich the core 3 and has grooves 15 of a shape that allows the core 3 and the penetration prevention plate 6 to be placed on the joint surface of each member. The width of the penetration prevention plate 6 is set larger than the width of the contact surface of the core 3 that contacts the penetration prevention plate 6.SELECTED DRAWING: Figure 1
【課題】変形時に芯材が木製の座屈拘束材を破損するのを防止でき、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、座屈拘束材５と芯材３との間に介在して芯材３が座屈拘束材５にめり込むのを防止するめり込み防止板６とを備えてなる座屈拘束ブレース１であって、芯材３は１枚の鋼板又は複数枚の鋼板を組み合わせてなる開断面部材からなり、座屈拘束材５は、芯材３を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とめり込み防止板６を配設可能な形状の溝部１５を有してなり、めり込み防止板６の幅は、めり込み防止板６に当接する芯材３の当接面の幅よりも大きく設定されている。【選択図】 図１
