Abstract

In this paper, an extensive comparative study of steel and FRP reinforcing bars in bridge construction is presented, the analysis is addressed concerning three major factors: performance, durability and cost. In light of growing interest in sustainable and high-performance infrastructure, this work supplements the existing knowledge base by providing direct comparisons of the two materials with respect to its structural adequacy, durability under long-term exposure in aggressive environmental conditions, and cost-benefit analysis. The research underlined, the better anticorrosion performance and reduced specific weight for FRP, which shows interest for modern design of the bridges, especially in the coastal and industrial regions where commonly the steel reinforcement deteriorates. Furthermore, a cost comparison is presented which gives a fair idea of the financial savings that might be obtained if FRP is used instead of steel and helping engineers, deciding authorities, and construction managers to take a rational decision. Using real-life examples, the study provides a practical insight that facilitates direct applicability of the results in bridge projects. It must also be noted that in addition to being cost effective, it is also environmentally responsible, with longer service life and decreasing operational maintenance required with FRP reducing the environmental footprint of infrastructure development. This research offers vitals idea to the construction sector, opening a new frontier to hybrid reinforcement strategies and advanced materials for sustainable infrastructure.
