Investigation of Cross-Sectional Dimension on Optimum Carbon Fiber Reinforced Polymer Design for Shear Capacity Increase of Reinforced Concrete Beams
In retrofit of reinforced concrete (RC) structures, the use of carbon fiber reinforced polymers (FRP) is an alternative way which is easily applied without destruction. In this study, the cross-section dimensions of beams are investigated for optimum parameters of CFRP such as spacing of CFRP, width of CFRP and angle of CFRP. The different combinations of cross-section dimension such as breadth (bw), height (h) and thickness of flange of T-shaped cross-sections (hf). The rules of ACI-318: Building code requirements for structural concrete was used in development of the total area of CFRP which is the objective function and penalized with three design constraints. The optimization method using Jaya Algorithm was used in the investigation. According to the results, the rise of bw increases the required CFRP area, but in the cases with big additional shear force, it provides a design without violation of design constraints. The increase of h has always a reduction of required areas.
