Life-Cycle Cost Evaluation of Neutralized Reinforced Concrete Bridges Subjected to Earthquake

For the reinforced concrete (RC) bridges, the deterioration of surface concrete caused by neutralization often leads to corrosion of the steel reinforcement. As neutralization progresses, the corrosion could become serious enough to endanger the structural performance of the bridges. The authors previous study has established some essential mathematical expressions and important parameters to predict the neutralization effect of existing RC bridges in Taiwan, such as the diffusive coefficients of neutralized concrete, the corrosive speed and corroded depth of the reinforcements, time for initial corrosion of the reinforcements, and time for cracking of cover concrete were be able to be evaluated. As a consequence, the performance degradation of the structure can be determined quantitatively. This paper will further make the study on the life cycle cost evaluation of the neutralized bridges subjected to earthquake. The results obtained will benefit the proposing of an optimum maintenance plan for the bridges.
