Abstract

The increasing need for long-lasting and sustainable infrastructure has encouraged the use of innovative materials in civil engineering applications. This study examines the design of a culvert reinforced with Fiber Reinforced Polymer (FRP) bars as a substitute for conventional steel reinforcement. FRP bars provide notable benefits such as excellent resistance to corrosion, a high strength-to-weight ratio, and improved durability. These properties make them especially appropriate for structures exposed to aggressive environmental conditions, including culverts, where long-term performance and reduced maintenance are critical.This study explores the structural design of a culvert incorporating FRP rebars to address the limitations of conventional materials, such as steel corrosion, which often compromises the durability of culverts. The design is based on guidelines provided by relevant codes and standards for FRP reinforcement. Key considerations include material properties, load-bearing capacity, deflection limits, and long-term performance under varying loads and environmental conditions.In addition to the design, a comparative analysis between steel-reinforced and FRP-reinforced culverts is conducted to evaluate the economic and environmental benefits. The results highlight the potential of FRP rebars in enhancing the durability and sustainability of civil infrastructure, with particular emphasis on cost-effectiveness over the structure's lifespan and reduced maintenance requirements.This project contributes to the ongoing efforts in adopting innovative construction materials that improve the durability, safety, and efficiency of essential infrastructure, paving the way for more resilient and sustainable designs.
