抄録

The theoretical solution of crack width in reinforced concrete members has been proposed by the authors in the previous paper, Part1. However, the theoretical solution is difficult to use routinely because the two parameters in the solution, tensile splitting strength of concrete and the bond stiffness, should be obtained from experimental result. Therefore, this research proposes the formula by simplified the theoretical solution. The practical formula for the tensile splitting strength from compressive strength was proposed by the previous study. In order to discuss the bond stiffness, the pullout test is conducted to propose the formula for it from compressive strength and diameter of reinforcing bar, which are the influence factors for bond stiffness. To use the formulas for tensile splitting strength and bond stiffness, the theoretical solution is simplified. The calculated relationships between reinforcement strain and crack width which are led by the proposed formula show good agreements with the theoretical solution.
