Flexural design of concrete beams reinforced with FRP rebars

Abstract The corrosion of steel rebars is the main cause reinforced concrete degradation, which results in increasing costs with structural rehabilitation and repairs. As a solution, resistant rebars, such as those FRP – Fiber-reinforced polymer –, have been used to replace conventional steel. This paper describes development design program that calculates flexural reinforcement T-shape beams. possibilities regards neutral axis position, failure mode linear or non-linear behavior define scenarios for their respective equations were deduced. strengths computed using deduced showed agreement experimental 125 beams, validating proposed methodology. Since are vulnerable creep rupture, sustained stresses must be lower than maximum allowed by ACI 440.1R-15, may require increases areas, modifying strength. Therefore, compute new depth strength based on adjusted area implemented computational program. Subsequently, this presents examples considering all one T-section different combined normal high-performance concretes also reported. beams aramid glass required large areas avoid whereas carbon considerably small; however, they exhibited small curvatures fragile when under-reinforced.
