Bond failure of deformed reinforcing bars generally takes place by splitting of surrounding cover concrete, unless they are confined by heavy reinforcements in surrounding. Therefore. bond strength of deformed reinforcing bars is determined by the cracking resistance of cover concrete. This paper presents analytical method the determine cracking strength of cover concrete by the finite element method where only the effect of tensile cracking is considered to simplify the failure structure of the model. The following results are obtained. 1. Progressive behavior of cracking and cracking strength of cover concrete are determined. 2. Radial stresses perpendicular to the surface of reinforcing bars are uniform before cracks start in concrete and become non-uniform after cracks develop.
