Abstract

This chapter provides a comprehensive procedure for the time-dependant structural performance evaluation and life-cycle cost analysis of reinforced concrete highway bridges located in extreme chloride-laden environments. The penetration of chloride ions into the concrete is simulated through a finite difference approach, which takes into account all the parameters that can affect the corrosion process. From simulation results, the corrosion initiation time is predicted and the extent of structural degradation is calculated over the entire life of bridge. A group of detailed bridge models with various structural attributes are developed to evaluate the changes in the structural capacity and seismic response of corroded bridges. For the purpose of the probabilistic seismic risk assessment of bridges, the seismic fragility curves are generated and updated at regular time intervals. The time-dependent fragility parameters are employed to investigate the life-cycle cost of bridges by introducing a performance index which combines the effects of probable seismic events and chloride-induced corrosion. The proposed approach provides a multi-hazard framework, which leads to more realistic performance and cost estimates. It also indicates the inspection and maintenance intervals in a way that the inspection and maintenance costs are optimized, while the safety of bridge is ensured.
