Reinforced Concrete (RC) and Prestressed Concrete (PC) structures using conventional materials in aggressive exposure conditions are susceptible to corrosion. Non-corrosive reinforcement materials such as: Glass Fiber-Reinforced Polymer (GFRP) rebars; Carbon Fiber-Reinforced Polymer (CFRP) strands; Stainless-Steel (SS); and Epoxy-coated steel (ECS) reinforcing bars, are attracting attention as more appropriate options in concrete structures. This paper addresses a Life Cycle Cost (LCC) analysis that verifies the cost performance of four different alternative reinforcement bars for the design of a demonstration FRP-RC/PC bridge in Florida, namely Halls River Bridge (HRB). The four different alternatives to be compared are namely Carbon Steel (CS), SS, FRP, and ECS, and the analysis is performed over 100-years. Additionally, a Life-Cycle Assessment (LCA) is included in the analysis to investigate the environmental credentials of the four design alternatives. Cost sensitivity analyses over specific parameters are included. The parameters analyzed are: reinforcement cost, changes in chloride concentration levels over the bridge service life, and discount rate values. Conclusions and recommendations for standard practices and design of future alternative solutions are then presented.

在侵蚀性暴露条件下使用常规材料的钢筋混凝土（RC）和预应力混凝土（PC）结构易受腐蚀。非腐蚀性增强材料，例如：玻璃纤维增​​强聚合物（GFRP）钢筋；碳纤维增强聚合物（CFRP）股；不锈钢（SS）；作为混凝土结构中更合适的选择，环氧树脂和环氧涂层钢（ECS）钢筋受到关注。本文介绍了生命周期成本（LCC）分析，该分析验证了佛罗里达州示范FRP-RC / PC桥，即Halls River桥（HRB）设计中四种不同替代钢筋的成本性能。要比较的四个不同替代方案是碳钢（CS），不锈钢，玻璃钢和ECS，分析进行了100年。另外，分析中包括生命周期评估（LCA），以研究四种设计替代方案的环境资质。包括对特定参数的成本敏感性分析。分析的参数为：加固成本，桥梁使用寿命中氯化物浓度水平的变化以及折现率值。然后介绍了标准做法和未来替代解决方案设计的结论和建议。
