The efficiency of Fiber Reinforced Polymer (FRP) materials for strengthening existing Reinforced Concrete (RC) structures according to the Near Surface Mounted (NSM) technique can be greater than the External Bonded Reinforcement (EBR) technique since the tensile strength of the FRP materials is in general better exploited. Firstly, this paper deals with analyzing the effect of the loading pattern on RC beams strengthened with both types of strengthening technique; in particular, two loading patterns have been used for the experimental tests on simple supported beams: 1) a four points bending scheme, and 2) a scheme with distributed loads, in order to check the sensitivity of failure modes and ultimate loads to different distributions of bending moment and shear along the beam. Then, a comparison between the results of flexural tests on RC beams strengthened with both NSM and EBR techniques is dealt with.

Abstract
The efficiency of Fiber Reinforced Polymer (FRP) materials for strengthening existing Reinforced Concrete (RC) structures according to the Near Surface Mounted (NSM) technique can be greater than the External Bonded Reinforcement (EBR) technique since the tensile strength of the FRP materials is in general better exploited. Firstly, this paper deals with analyzing the effect of the loading pattern on RC beams strengthened with both types of strengthening technique; in particular, two loading patterns have been used for the experimental tests on simple supported beams: 1) a four points bending scheme, and 2) a scheme with distributed loads, in order to check the sensitivity of failure modes and ultimate loads to different distributions of bending moment and shear along the beam. Then, a comparison between the results of flexural tests on RC beams strengthened with both NSM and EBR techniques is dealt with.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
