Abstract
This research leads the theoretical solution of crack width in reinforced concrete members based on the equilibrium of axial forces and compatibility conditions between concrete and reinforcement and the condition of crack occurrence. In the case of bi-linear bond stress - slippage relationship model, the theoretical solution of crack width is led as the relationship between loaded end strain of reinforcement and crack width. The pullout bond test and tensile bond test is conducted to investigate the adaptability of proposed method for deformed steel bar and AFRP reinforcement. The calculated relationship between reinforcement strain and crack width shows a good agreement with the experimental result.
