Abstract

Time-dependent reliability analysis has been used for the performance evaluation and maintenance planning of deteriorating reinforced concrete (RC) structures during their life-cycle. This paper presents an improved threshold-based approach for the rational scheduling and selection of maintenance actions for RC structures based on time-dependent reliability analysis, with particular application to the fiber-reinforced polymer (FRP) strengthening of RC bridge girders. The proposed approach is superior to existing approaches due to its consideration of time-dependent uncertainty in structural resistance in a computationally efficient manner. State-of-the-art deterioration models for FRP-strengthened RC bridge girders exposed to a marine environment are adopted to evaluate the time-dependent reliability of RC bridge girders before and after strengthening. The methodology is demonstrated in detail using a numerical example.
