BUCKLING RESTRAINED BRACE

To provide a buckling restrained brace capable of preventing interference between components and a hardener when a compressive force is applied to a member including a core in the longitudinal direction.SOLUTION: A disclosed buckling restrained brace includes: a member that includes a core member 10 and extends in the longitudinal direction; a restraint member 30 that coves the outer periphery of the member; a filler 31 filled between the member and the restraint member 30; and buffer members 40, 50. The member includes an inclined portion that is inclined to approach the central axis of the buckling restrained brace from the edge of the member to the center of the member. The buffer members 40, 50 are placed between the filler 31 and the inclined portion. The length of the core member 10 in the width direction which is the length of the buffer members 40 and 50 is longer than the length of the board width direction, which is the length of the inclined portion.SELECTED DRAWING: Figure 3 【課題】芯材を含む部材に長手方向の圧縮力が加わったときに、部材と硬化剤との干渉を防止することができる座屈拘束ブレースを提供すること。【解決手段】本開示に係る座屈拘束ブレースは、芯材１０を含み、長手方向に延びる部材と、部材の外周を覆う拘束部材３０と、部材と拘束部材３０との間に充填される充填剤３１と、緩衝部材４０、５０と、を備え、部材は、部材の端部から部材の中央部に向かうに連れて座屈拘束ブレースの中心軸へ近づくよう、傾斜する傾斜部を含み、緩衝部材４０、５０は、充填剤３１と傾斜部との間に配置され、緩衝部材４０、５０の長さであって芯材１０の板幅方向の長さは、傾斜部の長さであって板幅方向の長さより長い、ことを特徴とする。【選択図】図３
