METHOD FOR EVALUATING PROOF STRENGTH OF REINFORCED CONCRETE MEMBER
To provide a method for evaluating the proof strength of a reinforced concrete member, capable of properly evaluating the proof strength of a reinforced concrete member with a cut-off second main reinforcing bar.SOLUTION: Regarding a method for evaluating the proof strength of a reinforced concrete member in which concrete is cast into a reinforcing bar having a plurality of main reinforcing bars provided with shear reinforcing bars, the main reinforcing bar has a first main reinforcing bar arranged on an outer periphery and a second main reinforcing bar arranged on the center side with respect to the first main reinforcing bar. The middle of the second main reinforcing bar is cut off. Adhesion strength is a smaller value out of a value of adhesion splitting strength τand a value of adhesion removal strength τ, and the adhesion strength is equal to or larger than an adhesion stress degree experimental value τobtained in advance by an experiment.SELECTED DRAWING: Figure 5
【課題】２段目主筋がカットオフされた鉄筋コンクリート部材の耐力評価を適正に行える鉄筋コンクリート部材の耐力評価方法を提供する。【解決手段】複数の主筋にせん断補強筋が設けられた鉄筋に、コンクリートを打設した鉄筋コンクリート部材の耐力を評価する方法であって、主筋は、外周に配置された１段目主筋と、１段目主筋より中心側に配置された２段目主筋とを有し、２段目主筋の途中がカットオフされ、付着強度を、付着割裂強度τｂｕの値と付着抜け出し強度ταのうち小さい値とし、付着強度は、予め実験により求められた付着応力度実験値τexpと同じあるいは大きい。【選択図】図５
