%X Reinforced concrete (RC) structures often suffer from damage due to corrosion of reinforcing steel caused by carbonation and/ or chloride contamination of concrete. Cracks can be caused erosion of structures when the time of their formation is a main parameter on performance structures And it is important that be able to predict with sufficient accuracy. thus the time prediction of corrosion initiation up to crack formation in the concrete cover is so important .in order to investigation of accuracy of analytical models result is used reability nonlinear behavior of concrete and inability to account for actual location of corroding reinforcing bars, finite element model is applied. in this research in order to simulation of analytical and crack growth method finite element software (FE) is used. To verification designed models, experimental models is applied and results of experimental and numerical models were compared. Results shows that cover reinforcement bars and concrete compressive strength are effective factors of starting cracking and with increasing these two parameters, inner pressure due to corrosion production 4 or 5 time will increase.
