DESIGN METHOD FOR REINFORCED CONCRETE CONSTRUCTION, AND REINFORCED CONCRETE CONSTRUCTION
PROBLEM TO BE SOLVED: To provide a design method for reinforced concrete construction for making it possible to widen a living space.SOLUTION: An reinforcement amount of a main reinforcement 21 for a beam is calculated by taking a boundary part between a high strength part 211 and a normal strength part 212 apart from a root part R of a column-beam joint part of a beam, instead of the root part, as a position Q of a yield hinge in calculating a bending moment of the position Q of the yield hinge as a design bending moment. Or, taking the boundary part apart from the root part, instead of the root part, as the position Q of the yield hinge reduces the design bending moment, requiring less reinforcement amount. Requirement for less reinforcement amount makes it unnecessary to increase cross sectional area of the column-beam joint part, making it possible to widen a living space.SELECTED DRAWING: Figure 2
【課題】居住空間を広くすることができる鉄筋コンクリート造の設計方法を提供する。【解決手段】降伏ヒンジの位置Ｑの曲げモーメントを設計用曲げモーメントとして算定するにあたり、降伏ヒンジの位置Ｑを梁の柱梁接合部の付け根部ではなく、この付け根部Ｒから離れた高強度部分２１１と普通強度部分２１２との境界部として梁用の主筋２１の鉄筋量を求めた。つまり、降伏ヒンジの位置Ｑを、付け根部ではなく、付け根部から離れた境界部とすることで、設計用曲げモーメントが小さくなり、その分、鉄筋量が少なくてすむ。鉄筋量が少なくてすむので、柱梁接合部の断面積を大きくすることを要せず、そのため、居住空間を広いものにできる。【選択図】図２
