BUCKLING RESTRAINED BRACE, AND LOAD BEARING STRUCTURE
To provide a buckling restrained brace, and a load bearing structure allowing residual deformation after receiving axial deformation through an earthquake and the like to be reduced without any degradation of strength of buckling restrained brace itself.SOLUTION: A buckling restrained brace 1 is provided with a core member 2 and a restrained member 3, wherein the core member 2 comprises a first steel plate 21 having a first yield point, a second steel plate 22 having a second yield point different from the first yield point, and a third steel plate 23 having a third yield point different from the first yield point, the second steel plate 22 and the third steel plate 23 clamping the first steel plate 21 and a length of a first plasticized portion 21a of the first steel plate 21 in an axial direction being different from a length of a second plasticized portion 22a of the second steel plate 22 and a length of a third plasticized portion 23a of the third steel plate 23.SELECTED DRAWING: Figure 1
【課題】座屈拘束ブレース自体の強度は損なわないまま、座屈拘束ブレース自体の強度は損なわないまま、地震等により軸方向変形を受けた後の残留変形を低減することができる座屈拘束ブレース、及び耐力構造物を提供すること。【解決手段】座屈拘束ブレース１は、芯材２と、拘束部材３と、を備え、芯材２は、第１の降伏点を有する第１の鋼板２１と、第１の降伏点と異なる第２の降伏点を有する第２の鋼板２２と、第１の降伏点と異なる第３の降伏点を有する第３の鋼板２３と、を有し、第２の鋼板２２及び第３の鋼板２３は第１の鋼板２１を挟み込んでおり、第１の鋼板２１の第１の塑性化部２１ａの軸方向の長さは、第２の鋼板２２の第２の塑性化部２２ａの軸方向の長さと異なり、かつ第３の鋼板２３の第３の塑性化部２３ａの軸方向の長さと異なることを特徴とする。【選択図】図１
