Fiber Reinforced Polymers (FRP) reinforcement are increasingly common as internal reinforcement of Reinforced Concrete (RC) members, because of their excellent properties as high tensile strength, corrosion resistance and non-magnetization. However, the flexural and mechanical characteristics of FRP bars such as low modulus of elasticity or non-yielding characteristics, results in large values of deflection and wide crack of FRP RC element. This paper investigates and compares the Serviceability Limit State (ULS) of simply supported beam subjected to various values of flexural stresses. The beams reinforced with Carbon Fiber Reinforced Polymer (CFRP) and Aramid Fiber Reinforced Polymer (AFRP) bars were examined. The computational analysis of beams static work was based on American guide for the design (ACI 440.1R-06), with taking into consideration all reduction factors. The influence of various parameters as the reinforcement ratio or load level were analyzed.
