NON-LINEAR FINITE ELEMENT ANALYSIS OF REINFORCED CONCRETE (RC) BEAMS STRENGTHENED WITH CARBON FIBER

The major goal of this research is to use nonlinear finite element analysis to investigate the strengthening of reinforced concrete (RC) beams with CFRP. The models were created using ANSYS finite element analysis software, which was used to investigate the influence of key parameters on the response of reinforced RC beams under flexure and shear. Seven models were created, four for flexural strength and three for shear strength, taking into account the effects of two primary parameters: the number of CFRP layers and CFRP strengthening by continuous U-wrapping. The ANSYS results were in good agreement with the previous research's experimental findings. The ultimate capacity in shear and flexure improves for strengthened RC beams with CFRP layers and U-wrap, with U-warp proving to be more effective than CFRP layers.
