- The global flexural performance of reinforced concrete beams strengthened internally with Carbon Fiber Reinforced Polymer (CFRP) rods using the Side Near Surface Mounted (SNSM) technique is investigated using non linear finite element modelling in ABAQUS software. In this study, the CFRP rods are strategically placed laterally, adjacent to the longitudinal steel bars inside pre-cut grooves which are created in the concrete cover. After that, the groove is filled with an epoxy paste. The strengthening length and position of CFRP rods, bar diameter as well as groove size are the main parameters investigated in this study. Furthermore, the paper includes a comprehensive comparison between the Side Near Surface Mounted (SNSM) and Near Surface Mounted (NSM) techniques for the strengthening of RC beams using CFRP rods. This comparison aims to validate and assess the effectiveness of the SNSM technique in enhancing the structural performance of reinforced concrete beams. The study results revealed that the failure mode was affected by both the length and diameter of CFRP rods, whereas the variation of position of the rod from the neutral axis showed minor effect. The SNSM strengthening technique offers an alternative to the NSM method and helps to prevent the unconventional failure modes such as CFRP rod pull-out or premature debonding failure.
