Abstract: Three-dimensional finite element program which can perform the analyses of moisture transport, chloride attack, and steel corrosion simultaneously are developed. Each aspect is analyzed separately and successively, from the moisture transport to the steel corrosion, in order to simplify the analysis procedure and save the calculation time. Analysis priority for each aspect is determined from its influence to the other aspects, thereby the analysis error caused by ignoring the coupling effect can be minimized. After verifying the applicability of developed analysis program by performing a simulation analysis of Schießl's experiment, a model analysis was made in order to determine the critical parameter which governs the rate of steel corrosion at the crack in RC structures. Analysis results revealed that the resistance of concrete is the most important parameter which determines the corrosion acceleration near the crack.
