BRACE STRUCTURE
PROBLEM TO BE SOLVED: To provide a brace structure being high in a degree of freedom of design, by enhancing earthquake resistance of a structural frame, by preventing buckling of a brace body, by avoiding earthquake-time compressive force of acting on a brace.SOLUTION: A brace body 1 is composed of a brace body 2 and a pair of fixation metal fittings 3 and 4, and is joined by a plate joining pin 14 to upper-lower gusset plates 13a and 13b existing a diagonal position of a rectangular frame surface 10 of a steel frame, and joins the brace body 2 and the fixation metal fittings 3 and 4 by an intermediate part joining pin 15. Since both the plate joining pin 14 and the intermediate part joining pin 15 are arranged in the vertical direction to the rectangular frame surface 10, when compressive force P acts on the brace body 1 by horizontal force Q such as an earthquake, as a result of generating rotation in all pin joining parts, the brace body 1 bends downward in a position of the pin joining part, and compressive axial force can be avoided.SELECTED DRAWING: Figure 4
【課題】ブレースに働く地震時の圧縮力を回避してブレース本体の座屈を防ぎ、構造フレーム架構の耐震性を高め、設計の自由度が高いブレース構造を提供する。【解決手段】ブレース体１は、ブレース本体２と一対の定着金具３，４からなり、鉄骨架構の矩形状架構面１０の対角位置にある上下のガセットプレート１３ａ，１３ｂにプレート接合ピン１４でピン接合し、ブレース本体２と定着金具３，４を中間部接合ピン１５でピン接合する。プレート接合ピン１４と中間部接合ピン１５が、いずれも矩形状架構面１０に対して垂直方向に配置されるため、地震等の水平力Ｑによりブレース体１に圧縮力Ｐが作用したとき、すべてのピン接合部で回転が生じる結果、ブレース体１はピン接合部の位置で下方に屈曲し、圧縮軸力を回避することができる。【選択図】図４
