COLUMN BEAM FRAME IN REINFORCED CONCRETE
To provide a column beam frame in reinforced concrete capable of moving a flexure yielding hinge position of the beam toward a beam central side than conventional one, reducing damage of the column beam joint part and preventing a joint part yielding breakage in earthquake.SOLUTION: The column beam frame 1 comprises a column 10 in reinforced concrete and a beam 20 in reinforced concrete joined to the column 10. In the column beam frame 1 a first beam main reinforcement 60 arranged at a central part side of the beam 20 and a second beam main reinforcement 61 arranged at an end part side of the beam 20 are coupled at a reinforcement joint part 62 and the second beam main reinforcement 61 is a larger diameter reinforcement or a high strength reinforcement in a larger diameter compared to the first beam main reinforcement 60.SELECTED DRAWING: Figure 1
【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させて、地震時における柱梁接合部の損傷を低減し接合部降伏破壊を防止できる、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。柱梁架構１は、梁２０の中央部側に配置された第１の梁主筋６０と、梁２０の端部側に配置された第２の梁主筋６１とが、鉄筋継手部６２で連結され、第２の梁主筋６１は、第１の梁主筋６０に比べて、太径鉄筋または太径の高強度鉄筋である。【選択図】図１
