BUCKLING RESTRAINT BRACE
To provide a buckling restraint brace that can exhibit stable performance while suppressing damage to an unbonded portion provided between a core material and a buckling stiffening material and an associated local buckling of a core material.SOLUTION: A buckling restraint brace 1 comprises: a steel core material 2; a buckling stiffening material 3 comprising a cylindrical outer steel material 4 provided to cover the core material 2 from the outside and a cement-based filling portion 5 provided inside the outer steel material 4; and an unbonded portion 7 provided between the core material 2 and the cement-based filling portion 5. The unbonded portion 7 comprises: a deformation absorption layer 8 provided on a surface 2s of the core material 2 and absorbing deformation of the core material 2; and a sliding layer 9 provided between the deformation absorption layer 8 and the cement-based filling portion 5 so as to be able to slide freely with respect to the cement-based filling portion 5.SELECTED DRAWING: Figure 2
【課題】芯材と座屈補剛材の間に設けられたアンボンド部の損傷とこれに伴う芯材の局部座屈を抑制しつつ、安定した性能を発揮することができる、座屈拘束ブレースを提供する。【解決手段】座屈拘束ブレース１は、鋼製の芯材２と、芯材２を外側から覆うように設けられ、筒状を成す外側鋼材４と、外側鋼材４の内側に設けられたセメント系充填部５と、を備えている座屈補剛材３と、芯材２とセメント系充填部５との間に設けられたアンボンド部７と、を備え、アンボンド部７は、芯材２の表面２ｓに設けられ、芯材２の変形を吸収する変形吸収層８と、変形吸収層８とセメント系充填部５との間に設けられ、セメント系充填部５との間で滑動自在となるように設けられた滑動層９と、を備えている。【選択図】図２
