CIV5887: FRP Strengthening of Metallic Bridges - Literature Review

This report presents a literature review on the application of Fiber Reinforced Polymers (FRP) for strengthening metallic bridges. It explores the advantages of FRP materials, including their high strength-to-weight ratio and resistance to environmental degradation, making them suitable for bridge rehabilitation and new construction. The review covers various aspects, such as the use of FRP in different bridge components, fatigue failure, and case studies like the Acton and Corona bridges. The research highlights the importance of innovative techniques like prestressed FRP overlays and the significance of bond strength between FRP and steel surfaces. The paper also discusses various tests and studies conducted to determine the effectiveness of FRP in enhancing the load-carrying capacity and extending the lifespan of metallic bridge structures. The report analyzes the impact of FRP on the bridge's service life. The review concludes by emphasizing the potential of FRP as a cost-effective and efficient solution for maintaining and improving the performance of existing metallic bridges, especially those facing fatigue-related issues.
