BUCKLING RESTRAINT BRACE
To provide a buckling restraint brace capable of preventing the occurrence of a drop-off of a member or a non-reinforcable area when a core material deforms while achieving the same effects of adjusting the axial force of the core material and suppressing the decrease in strength in the strong axis direction by a conventional structure in which a spacer is inserted into a slit in a core material.SOLUTION: A buckling restraint brace 100 includes: a steel plate core material 10; a pair of restraining materials 30 composed of a square steel pipe arranged facing two wide surfaces 10a of the core material 10; and an unbonded material 20 interposed between the core material 10 and the restraining material 30. In the wide surface 10a of the core material 10, one through hole 16 and two notches 17 that communicate with the through hole 16 each extending in the longitudinal direction of the core material 10 on both sides of through hole 16, and the through hole 16 and the notches 17 constitutes the axial force adjustment means of the core material 10.SELECTED DRAWING: Figure 1
【課題】芯材に設けられているスリットにスペーサーが内挿される従来構造による、芯材の軸力調整と強軸方向の強度低下抑制といった同様の効果を享受しながら、芯材の変形の際の部材の抜け落ちや補剛不能領域の発生を防止できる、座屈拘束ブレースを提供すること。【解決手段】鋼製でプレート状の芯材１０と、芯材１０の有する２つの広幅面１０ａに対向するように配設されている、角形鋼管からなる一対の拘束材３０と、芯材１０と拘束材３０の間に介在するアンボンド材２０とを有する、座屈拘束ブレース１００であり、芯材１０の広幅面１０ａには、１つの貫通孔１６と、貫通孔１６に連通して貫通孔１６の左右の両側においてそれぞれ芯材１０の長手方向に延びている２つの切り込み１７とが設けられており、貫通孔１６と切り込み１７が芯材１０の軸力調整手段を形成している。【選択図】図１
