破砕剤充填パイプにより鉄筋腐食ひび割れを模擬した鉄筋コンクリートの残存付着強度

・This study empirically investigates the bond strength degradation in cracked concrete. The combined effects of concrete cracking and cross-sectional reduction of stirrups on bond capacity are considered.
・Bond strength decreases when the induced crack width increases.
・We also propose to estimate bond strength degradation as a function of the induced crack width and stirrup ratio.
