Abstract
While lots of harbor structures have been constructed, some of them are reaching the ends of design service life. The number of structures at which remedial actions are required will be increasing rapidly. To meet the increasing number of degraded structures, strategic maintenance and repair methods should be implemented to realize life extension and structural performance recovery, resulting in minimization of life-cycle costs.In this paper, the method is proposed to evaluate proper life-cycle scenario of deteriorated open-type wharf from the viewpoint of life-cycle cost. The change in load carrying capacity of RC members due to rebar corrosion is taken into account. Based on the calculated results, life-cycle scenarios with different repair plans were discussed from the viewpoints of recovery of load carrying capacity and the relevant life-cycle cost.
