Zusammenfassung: | To employ a mechanical anchorage method to an axial reinforcement by laying a strengthening reinforcement extending in parallel with the axial reinforcement having a mechanical anchorage member at a reinforcement concrete column/beam joining part, to move a damaged point resulting from a yield of the reinforcement to a span center side of a column, and to improve deformation performance.SOLUTION: A reinforcing concrete structure comprises concrete 21, an axial reinforcement embedded into the concrete 21, and a strengthening reinforcement 12 embedded into the concrete 21 while being at least partially overlapped on the axial reinforcement. The axial reinforcement includes a mechanical anchorage member attached to its tip, and the strengthening reinforcement 12 extends in parallel with the axial reinforcement at the inside of the axial reinforcement over an indispensable overlap range which is not shorter than a length necessary for transmitting a tensile force which is received by the axial reinforcement.SELECTED DRAWING: Figure 6
【課題】鉄筋コンクリート柱梁接合部における機械式定着部材を有する軸方向鉄筋と並んで延在する補強鉄筋を配設することによって、軸方向鉄筋に機械式定着工法を採用することができるとともに、鉄筋の降伏に起因する損傷箇所を柱のスパン中央寄りに移動させることができ、変形性能が向上するようにする。【解決手段】コンクリート21と、該コンクリート21に埋め込まれた軸方向鉄筋と、該軸方向鉄筋と少なくとも一部がオーバーラップして前記コンクリート21に埋め込まれた補強鉄筋12とを備え、前記軸方向鉄筋は先端に取り付けられた機械式定着部材を含み、前記補強鉄筋12は、前記軸方向鉄筋の受ける引張力が伝達されるために必要な長さ以上の必須オーバーラップ範囲に亘って、前記軸方向鉄筋の内側において、該軸方向鉄筋と並んで延在する。【選択図】図6 |
