The crack formation as a typical damage phenomenon in the reinforced concrete structures can not be avoided. The structural engineer in the practice however gives efforts to limit the width of cracks according to design standards. The cracking behavior in a reinforced concrete member with normal strength of concrete may have been sufficiently investigated and design standards, e.g. ACI-Building Code, CEB-FIP MC90, suggest some formulas to determine the crack behavior e.g. crack space, crack width, transfer length, tension stiffening effect. However, there is no limit to the use of these formulas regarding the concrete strength. The purpose of this paper is to review the prediction formulas for tension cracking behavior suggested in design standards for the high strength of concrete. A numerical model in a crack element with a given length will be formulated in which the cracking behavior can be investigated in detail. Results from the numerical analysis will be compared with them of experiments.
