Efficiency of CFRP NSM strips and EBR plates for flexural strengthening of RC beams and loading pattern influence

Therefore, the results of flexural tests on RC beams strengthened with both NSM and EBR techniques are discussed in this paper to show that the debonding phenomena for NSM strip strengthened beams are less significant than for EBR plate beams. Moreover, the effect of the loading pattern is analysed to evaluate the sensitivity of failure modes and loads to different distributions of bending moment and shear along the beam. Finally, the experimental results are compared with the predictions of theoretical models and code provisions.
