Numerical Investigation and Cost Analysis of FRP-Concrete Unidirectional Hybrid Slabs

Abstract Fiber-reinforced polymer (FRP) has been commonly used to reinforce concrete structures. The kinds of FRP demonstrate an effective alternative various methods reinforcement in structures subjected bad environmental conditions which cause corrosion and damage concrete. Due their lightweight, high strength, fatigue resistance, Fiber Reinforced Polymer composites have widely applied steel substitution during revitalization interventions. This paper presents numerical three-points bending tests on different models investigate the effect reinforcements; Carbon, Glass, Aramid fibers find corresponding cost each one. Also, there is available experimental model for verifying results FEM that demonstrated broad agreement with statement, concerning load-displacement curve. After validating models, designs such as type FRP, position amount usage were numerically tested study influence load-bearing capacity. showed best configuration would be one GFRP capacity around 9 kN optimum design.
