New parameter design of GFRP RC beams

Fiber Reinforced Polymer (FRP) is an advanced composite material that has been identified as a potential new construction material. Since it is a non-corrosive material it may be used as reinforcement in concrete member. However, there is limited experience with the design and construction of GFRP reinforced concrete structures. This paper presents an investigation of reinforced concrete beams with Glass Fiber Reinforced Polymer (GFRP). Six concrete beams reinforced with GFRP and steel bars were cast and tested to study their flexural behavior. The results of this investigation proposed a reinforcement ratio and should guide structural engineers to a cost-effective design of GFRP reinforced concrete members. In addition, comparisons with steel reinforced concrete section were also investigated.
