REINFORCING BAR CONCRETE FRAME AND STRUCTURE
To provide a reinforcing bar concrete frame which is provided with a column, a short span beam, and a bearing wall, and in which it is possible to reduce a column width while ensuring yield strength and deformation performance.SOLUTION: A frame of reinforcing bar concrete comprises a pair of reinforcing bar concrete subsidiary columns 21, a reinforcing bar concrete boundary beam 22 which connects top parts of the subsidiary columns 21, and a reinforcing bar concrete earthquake-resisting wall 20 joined to the pair of subsidiary columns 21. A material axis length L3 of the boundary beam 22 is shorter than a width L2 of the earthquake-resisting wall 20. Concrete bodies 30, 40, 50 for the subsidiary column 21, the boundary beam 22, and the earthquake-resisting wall 20 are formed with steel fiber reinforcement concrete in which steel fibers are mixed in an amount of 0.3-2.0% with respect to the concrete volume. A width W1 of the subsidiary column 21 is identical to a wall thickness W2 of the earthquake-resisting wall 20.SELECTED DRAWING: Figure 4
【課題】柱、短スパン梁および耐力壁を含む鉄筋コンクリート造架構について、耐力と変形性能を確保しつつ柱幅を小さくできる、鉄筋コンクリート造架構を提供すること。【解決手段】鉄筋コンクリート造の架構は、一対の鉄筋コンクリート造の付帯柱２１と、付帯柱２１の頂部同士を連結する鉄筋コンクリート造の境界梁２２と、一対の付帯柱２１に接合された鉄筋コンクリート造の耐震壁２０と、を備える。境界梁２２の材軸長さＬ３は、耐震壁２０の幅Ｌ２よりも短い。付帯柱２１、境界梁２２、および耐震壁２０のコンクリート体３０、４０、５０は、鋼繊維がコンクリート体積に対して０.３％以上２．０％以下混入された鋼繊維補強コンクリートで形成されている。付帯柱２１の幅Ｗ１は、耐震壁２０の壁厚Ｗ２と同一である。【選択図】図４
