Aggressive environment and in-service loading can cause the resistance deterioration of existing reinforced concrete structures. It is necessary to formulate time-deppendent reliability analysis on account of developing the rational maintenance strategy and reliable prediction of service life of deteriorating structures. In this study, the reliability function of deteriorating reinforced concrete structures due to aging under load combination consisting of dead, live and main external loads of earthquake is analytically investigated, applying the advanced first order and second moment method with the statistics of the residual resistance of each element of systems which has survived up to timer. The results by proposed method show comparatively good agreement In comparison with those by Monte Carlo simulation.
