BUCKLING RESTRAINING BRACE
PROBLEM TO BE SOLVED: To ensure absorption performance of vibration energy, while reducing overall weight.SOLUTION: A buckling restraining brace 10 includes an H-section steel 12 and a stiffener 14. The stiffener 14 includes a sheath tube 16 from which both edge parts of the H-section steel 12 extends at both ends, an inserted plate 18 extending along the H-section steel 12, and a filler 34 filled in a space partitioned between an outer surface of an assembly comprising the H-section steel 12 and the inserted plate 18 and an inner surface of the sheath tube 16. A non-filled space 36 is partitioned inside the assembly, where the filler 34 is not filled. Since a plasticized part A1 constituted by an intermediate part of the H-section steel 12 comprises a small cross-section part 28 having a small cross-section area, axial force borne by the bucking restraining brace 10 is reduced. Thus, a leeway is generated with regard to load bearing capacity of a non-plasticized part A0 compared to the plasticized part A1, enhancing the load bearing capacity of the overall buckling restraining brace 10 including the non-plasticized part A0 on both ends.SELECTED DRAWING: Figure 2
【課題】軽量化を図りつつ振動エネルギの吸収性能を確保する。【解決手段】座屈拘束ブレース１０はＨ形鋼１２と補剛材１４とを備える。補剛材１４は、Ｈ形鋼１２の両端部分がその両端から延出する外套管１６と、Ｈ形鋼１２に沿って延在する内挿板１８と、Ｈ形鋼１２と内挿板１８とから成るアセンブリの外側面と外套管１６の内側面との間に画成された空間に充填された充填材３４とを備える。アセンブリの内部に、充填材３４が充填されない非充填空間３６が画成されている。Ｈ形鋼１２の中間部分からなる塑性化部分Ａ１が断面積が小さい小断面積部２８で構成されているので、座屈拘束ブレース１０の負担軸力を減らすことで、塑性化部分Ａ１に対して非塑性化部分Ａ０の耐力に余裕が生じ、両端の非塑性化部分Ａ０を含めた座屈拘束ブレース１０全体の耐力を高めることができる。【選択図】図２
