ARRANGEMENT STRUCTURE OF BEAM IN REINFORCED CONCRETE COLUMN AND BEAM FRAME
PROBLEM TO BE SOLVED: To arrange a single reinforcing beam equivalent to a layered beam at each main reinforcement even if the main reinforcements at a lower end and an upper end are arranged in two stages when forming a hinge which is formed at a yield of the beam in a position shifted to an axial center side of the beam from a boundary face between a beam end part and a joining part, and to uniformly form a plastic hinge in a specified point which is shifted to a beam side from the column/beam joining part, in the reinforced concrete column/beam joining part.SOLUTION: A reinforcing beam 4 having a length reaching at least a beam 2 from a joining part 3, and formed with a hook 4a at an end part at least at one side in an axial direction is arranged along a main beam 21, and the hook 4a is positioned in the beam 2. In particular, the hook 4a is directed to a vertical direction, and the reinforcing beams 4 are aligned in parallel at a sideway of the main beam 21. If necessary, pouring beams 5 engaged with the hooks 4a of a plurality of the reinforcing beams 4 which are aligned in parallel in a width direction of the beam 2 are arranged with their axial directions directed toward the width direction of the beam 2.SELECTED DRAWING: Figure 1
【課題】鉄筋コンクリート造の柱・梁接合部において、梁の降伏時に形成されるヒンジが梁端部と接合部との境界面より梁の軸方向中心側へ寄った位置に発生するようにする上で、下端と上端の梁主筋が２段に配筋される場合にも各梁主筋に１本の、重ね筋に相当する添え筋を配筋することと、柱・梁接合部から梁側へ移行した特定箇所に一様に塑性ヒンジを形成することを可能にする。【解決手段】少なくとも接合部３から梁２までに跨る長さを持ち、少なくとも軸方向一方側の端部にフック４ａが形成された添え筋４を梁主筋２１に添って配筋し、フック４ａを梁２中に位置させる。特にフック４ａを鉛直方向に向け、添え筋４を梁主筋２１の脇に並列させて配筋する。場合により梁２の幅方向に並列する複数本の添え筋４のフック４ａに係合する流し筋５を、軸方向を梁２の幅方向に向けて配筋する。【選択図】図１
