Life Cycle Cost Analysis of Reinforced Concrete Highway Bridges in Chloride Contaminated Environments
The estimation of life cycle cost of a reinforced concrete bridge is critical in choosing an optimized inspection and maintenance program. This estimation becomes more important when the bridge is located in chloride contaminated environments under the chloride-induced corrosion. The present paper studies the total life cycle cost of typical bridges under different corrosion scenarios. The uncertainties associated with the estimation of corrosion initiation time are discussed and their effects on the calculation of bridge life cycle cost are evaluated through a probabilistic approach. Furthermore, the influences of decision-making parameters, such as inflation rate and expected life cycle, are considered to provide a broader view of budget allocation requirements. The total life cycle cost of bridge is calculated from the present value of construction cost, inspection and maintenance costs, serviceability failure costs, and associated user costs. The mentioned costs are reviewed in detail and their relevant assumptions are examined to obtain a more realistic estimation of total cost considering various inspection and maintenance strategies.
