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; and a pair of restraining materials 30 composed of a square steel pipe arranged facing two wide surfaces 10a of the core material 10. A first unit 15A and a second unit 15B are provided to form the axial force adjustment means of the core material 10. The first unit 15A has one through hole 16 A and two notches 17 that communicate one through hole 16A and extending in one side. The second unit 15B has one through hole 16B and two notches 17 which communicate with the one through hole 16B and extending on both left and right sides thereof.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とを有する、座屈拘束ブレース１００であり、芯材１０の軸力調整手段を形成している第１ユニット１５Ａと第２ユニット１５Ｂが設けられ、第１ユニット１５Ａは、１つの貫通孔１６Ａと貫通孔１６Ａに連通してその一方側に延びている２つの切り込み１７を備え、第２ユニット１５Ｂは、１つの貫通孔１６Ｂと貫通孔１６Ｂに連通してその左右の両側に延びている２つの切り込み１７を備えている。【選択図】図１
