Performance Evaluation of Glass Fiber-Reinforced Polymer (GFRP) Bars in Bridge Decks
https://orcid.org/https://orcid.org/0000-0001-5677-6324
Glass fiber-reinforced polymer (GFRP) bars have been used as a viable environment-friendly alternative to the steel reinforcement in bridge decks. The GFRP bars have comparable structural performance while providing a non-corrosive option for corrosion-prone-reinforced concrete bridge decks. This study presents the results of the performance evaluation of two similar bridge decks, one reinforced with GFRP bars and the other one reinforced with steel bars. The two bridges were instrumented using several vibrating wire strain gauges to collect their long-term data over time in response to the seasonal temperature changes. The GFRP bars were also tested in the lab to extract their stress–strain behavior and compare their mechanical properties to those of the conventional steel. Finally, the two bridge decks were compared in terms of economical characteristics through a set of life-cycle cost analysis based on the initial cost, bridge deck reconstruction, and also repair and rehabilitation costs during the service life of the bridges. The study revealed no concerning difference between the structural performance of a GFRP-reinforced and a steel-reinforced bridge decks, showing that GFRP bars could be used as a viable alternative material in bridge decks.
