Abstract

A maintenance planning method of a reinforced concrete deck bridge under chloride contaminated environment based on minimizing of the expected total life-cycle cost, namely the expected total LCC while maintaining the allowable lifetime reliability is developed. With this method, a lifetime optimization methodology for planning of the inspection and repair of the bridge that deteriorate over time is able to be numerically discussed. In this study, the effects of the timing of the inspection and repair of structures on the total life-cycle cost was especially investigated on the basis of the relationship between the amounts of the corrosion of steel rods and the crack width of the concrete.
