The crack width can be calculated by numerical calculation based on bond analysis, however, it is necessary to assume the local bond stress versus slippage relationship for calculation. The local bond stress – slippage relationship is the dominant factor of controlling crack width and spacing, so to comprehend the relationship is absolutely imperative for predicting the crack width and spacing. In this study, the local bond stress – slippage relationship obtained from pullout loading test is modeled by bi-linear model and the crack width and spacing is calculated by bond analysis based on the model. The analytical results of the crack width can represent the experimental results. The parametric bond analysis is performed to investigate the influence of elastic modulus and local bond stress versus slippage relationship on the crack width. In consequence, it is identified that not only elastic modulus but also the local bond stress – slippage relation ship influences the crack width. On the basis of these results, the calculation figure for crack width and spacing is proposed as the prediction method for them.
