Case Studies on the Use of Noncorrodible Materials for Sustainable Structures

This paper presents a series of case studies that explore the application of noncorrodable reinforcement materials, specifically Fiber-Reinforced Polymer (FRP) bars, in sustainable tunnel construction. The study highlights the advantages of using FRP, including its corrosion resistance, lightweight characteristics, and high tensile strength, which contribute to enhanced durability and reduced maintenance needs in underground environments. Through detailed examinations of various projects, this research illustrates the practical benefits and challenges associated with FRP reinforcement in tunnel applications. The findings indicate that while initial costs may be higher, the long-term performance improvements and sustainability benefits position FRP as a viable alternative to traditional steel reinforcement in tunnel design and construction.
