Shear And Flexural Behavior of Lightweight Self-Consolidating Concrete I-Beams Reinforced with Glass- And Basalt-FRP Bars

Research is committed to developing innovative solutions to meet the demands of the construction industry in a scientific base. New engineering processes are established, through investigations and research, to improve quality, design and product cost. Integrating fiber-reinforced polymer (FRP) bars into lightweight self-consolidating concrete (LWSCC) would effectively contribute to producing lighter and more durable reinforced concrete (RC) structures. This research addresses the feasibility of using FRP reinforcement in LWSCC I-beams taking into consideration the effect of fiber dosage in order to enhance the structural performance, time efficiency and optimised-cost. Full-scale precast LWSCC I-beams will be tested as simple beams to determine their flexural and shear capacity. The test parameters include the beam configuration, fiber dosage, longitudinal reinforcement ratio, type of reinforcement (Glass, Basalt FRP, and Steel bars) and type of concrete (LWSCC, fiber-reinforced LWSCC (FLWSCC), and normal weight concrete (NWC)). The experimental results will be discussed in terms of cracking behavior, the concrete strain, bar strain, crack width, curvature, deflection, flexural capacity, concrete shear strength, and mode of failure.
