Based on the calculation results from the finite element analysis, the concrete cracking progress and mechanism due to the corrosion of reinforcing bars in concrete are investigated. A relation is proposed between the internal concrete cracking, the external concrete cracking and the amount of the radial expansive deformation representing the amount of steel corrosion. The effect of two main parameters, the ratio of the concrete cover to the steel diameter, and the non-uniform corrosion, is discussed.
