Evaluation of flexural capacity of hybrid reinforced concrete beams made with fiber reinforced polymer rebars

The building industry’s ever-changing dynamics have resulted in the introduction of new materials from time to time. Glass fiber reinforced polymer (GFRP) bars are gradually replacing traditional steel bars in RCC work. The traditional structures are much affected with corrosion which reduces the long-term performance in terms of flexural capacity and hence FRP (fiber reinforced polymer) are introduced in the study as they are lightweight, high tensile strength, nonmagnetic. The most disadvantage of the FRP bar is the Brittleness. Hence Hybrid reinforcement is induced to improve flexural performance and ductility. This project work was studied on a different type of FRP bars, their mechanical properties, and effectiveness. Hence from the study, it is known that GFRP is the most effective in terms of cost and performance. The adaptability of GRRP, which has a higher strength-to-weight ratio, corrosion resistance, durability, and stiffness than traditional steel bars, is responsible for this significant shift in construction practice. However, because GFRP is prone to rapid and brittle failure due to its linear stress-strain behavior, reinforcing fibers are utilized in combination to offer structural safety.
