Abstract

Fiber reinforced polymers (FRPs) in combination with reinforced portland cement concrete (RPCC) beams (hybrid beams) exhibit greater moment bearing capacity and smaller deflections, respectively. A superposition model for the moment bearing capacity, using the rectangular stress block and the parabolic stress strain distribution is developed. Three prospective materials, kevlar fiber reinforced polymer (KFRP), carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) are investigated for relative improvement of moment bearing capacity of the hybrid structures. Sensitivity analysis was performed to illustrate the safety factor for hybrid beams as compared to RPCC beams.
