COLUMN-BEAM FRAME
To provide a reinforced-concrete column-beam frame that, when a flexural yielding hinge position of a beam is moved to a beam central part side as compared to a conventional one, can restrain extension of a crack.SOLUTION: A column-beam frame 1 comprises a reinforced-concrete column 10 and reinforced-concrete beams 20 joined to the column 10. Beam main reinforcements 30 of the beam 20 are constituted of first beam main reinforcements 30A that are penetrated to a column-beam joint part 11 of the column 10 and placed at a beam end part 20A, and second beam main reinforcements 30B provided at a beam central part 20B of the beam 20. The first beam main reinforcements 30A are provided with bundled reinforcements 41 which bundle multiple pieces of closed type stirrups 40 placed so as to surround first stage main reinforcements 31, 33 placed at upper and lower end sides of the beam 20 and second stage main reinforcements 32, 34 placed at inner sides of the beam 20.SELECTED DRAWING: Figure 2
【課題】梁の曲げ降伏ヒンジ位置を従来よりも梁中央部側に移動した場合に、ひび割れの伸展を抑制できる、鉄筋コンクリート造の柱梁架構を提供すること。【解決手段】柱梁架構１は、鉄筋コンクリート造の柱１０と、柱１０に接合された鉄筋コンクリート造の梁２０と、を備える。梁２０の梁主筋３０は、柱１０の柱梁接合部１１を貫通して梁端部２０Ａに設置される第１梁主筋３０Ａと、梁２０の梁中央部２０Ｂに設けられた第２梁主筋３０Ｂと、で構成される。第１梁主筋３０Ａには、梁２０の上下端側に配置される一段目主筋３１、３３と、梁２０の内部側に配置される二段目主筋３２、３４と、を囲むように配置される閉鎖型のスタラップ４０を複数本束ねた束ね筋４１が設けられる。【選択図】図２
