To provide an axial force resistant member capable of improving plastic deformability and energy absorption capacity under tensile load while maintaining high buckling resistance under compressive load.SOLUTION: An axial force resistant member includes a brace core material 2 which bears tensile and compressive loads, and a buckling restraining material 3 which prevents buckling of the brace core material 2 at the time of compression in which the brace core material 2 is yield-deformed by tensile and compressive loads. The brace core material 2 has a yield part 2A to be yield-deformed by tensile and compressive loads, and has fixing parts 2B, 2C to the buckling restraining material 3 at both end parts of the yield part 2A. At the end of the fixed parts 2B, 2C, there are provided attachment parts 4 and 5 to the structural member. A notch part 7, 7 is provided at an edge part at a boundary between a horizontal flange 6a of the fixing part 2B and the attachment part 4. A buckling reinforcing rib 8 is provided on a side face of the attachment part 4. The buckling reinforcing rib 8 has a face touch with the end face of the vertical flange 6b of the fixing part 2B on a vertical plane perpendicular to the axis perpendicular direction of the brace core member 2, which intersects with the notch parts 7, 7.SELECTED DRAWING: Figure 4
【課題】圧縮荷重時の高い座屈耐力を保持しつつ、引張り荷重時の塑性変形能力とエネルギー吸収能力を向上させた耐軸力部材を提供する。【解決手段】引張り及び圧縮荷重を負担するブレース芯材2と、引張り及び圧縮荷重によって降伏変形する圧縮時のブレース芯材2の座屈を防止する座屈拘束材3を有する。ブレース芯材2は引張り及び圧縮荷重によって降伏変形する降伏部2Aを有し、降伏部2Aの両端部分に座屈拘束材3への固定部2B,2Cを有する。固定部2B,2Cの端部に構造部材への取付け部4と5を有する。固定部2Bの水平フランジ6aと取付け部4との境目における縁端部に切欠き部7,7を有する。取付け部4の側面に座屈補強リブ8を有する。座屈補強リブ8は、切欠き部7,7と交差する、ブレース芯材２の軸直角方向の垂直な面で、固定部2Bの垂直フランジ6bの端面と面タッチするように有する。【選択図】図４
