Existing reinforced concrete (RC) structures require strengthening for various reasons such as errors in the originality design or construction, deterioration, structural damages like fire, excessive wear, excessive loading. The total replacement of structures needs high cost, and strengthening has become the best way for improving the load carrying capacity of the structural members and extending their service lives. In strengthening solution, lightweight and corrosion resistant materials are suitable. The near surface mounted (NSM) and externally bonded (EB) techniques are suitable approach for the enhancement of the flexural performance of the RC beams. In this research, the performance of NSM at the bottom and at the side of the RC beams, EB and a hybrid of both NSM and EB techniques for flexural strengthening of RC beams are compared. The use of U–warp as an end anchorage to delay the premature debonding failure of NSM bars at the end has also been presented. Experimental and analytical studies carried out to explore the performance of RC beams strengthened with the NSM bars and fiber strips, EB fiber sheet and composite of both NSM bars and EB fiber sheet. The analytical model were developed in predicting the cracking load, ultimate load and ultimate deflection. A three point bending test was applied on beams strengthened with different methods. The ultimate load capacity and failure mode of the beams were evaluated based on the experimental output. The test result indicates an increase in the cracking load capacity ranged between 31.66 % and 71.09% and in increase in the ultimate load capacity ranged between 10.34% and 43.45% compared to control beam.
