Prediction of Crack Width and Bond Stress-Slip Relationships in Reinforced Concrete Members

This study deals with the estimation of the crack width by stabilized cracking considering bond-slip relationships in reinforced concrete members. The proposed method utilizes the sameness of tension stiffening and a change of bond-slip relationships because of concrete's splitting. The validity, accuracy and efficiency of the proposed method are established by comparing the analytical results with the experimental date and the major code spcifications. The analytical results of analysis presented in this study indicate that the proposed method can be effectively estimated the crack width of the reinforced concrete members.
