Abstract

Some existing pile-supported wharves need to be repaired because of the insufficient countermeasures against corrosion. However, total amount of budget to be spent for maintaining the civil engineering works is reducing year by year. Therefore, it is very important to obtain the optimal repair strategy of the deteriorating structures. In this study, we discuss the optimal repair strategy of the existing pile supported wharf from the viewpoint of minimizing the expected total cost, which is defined as the multiplication of the failure probability and the repair cost. We conducted the reliability analyses and evaluated the failure probability of the pile-supported wharf in accordance with the repair strategy.
