This paper shows deterioration models due to carbonation in consideration of uncertainty to estimate the initiation and the rate of corrosion, and to analyze the structural capacity and serviceability of RC building, i.e. shear capacity, bending strength and width of severe cracking or spalling of columns and beams with corroded reinforcing bars based on simple formulas formed through the past experiments. Then, the failure probability due to earthquake, the probability that severe cracking or spalling will occur and the deterioration risk of deteriorated building in subsequent years from construction can be evaluated by probabilistic method. By applying immune algorithm to minimization of life-cycle cost including the deterioration risk, the optimal maintenance plan of reinforced concrete buildings can be found and a case study is finally conducted to prove this system.
