Chloride induced corrosion is the main cause of deterioration of reinforced concrete structures in marine environment. Corrosion damages require huge expenses to be repaired. Thus, it is required to design structures that need less repair in their life. A model to estimate Life-Cycle-Cost (LCC) of reinforced concrete structure in marine environment is proposed to be used as either an evaluation tool of a certain design, or as selection tool between suggested designs. It is concluded that life-cycle-cost analysis is an important tool to be used in assessing different specifications. Also, basing the decision upon the initial investment only can lead to an erroneous judgment. The total cost through the intended life has to be considered to choose the cost-effective solution as low initial investment can mean high maintenance and repair cost where the total cost may exceed high investments with low maintenance and repair costs. |
