| Abstract | To appraise the performance of the Near surface mounted (NSM) technique with carbon fiber reinforced polymer (CFRP) laminates for the shear strengthening of reinforced concrete (RC) beams having a certain percentage of existing steel stirrups, an extensive experimental research was carried out. The influence on the effectiveness of the NSM shear strengthening technique of the following parameters was investigated: the concrete strength; the percentage of existing steel stirrups; the percentage and orientation of the CFRP laminates. To evaluate the influence, on the strengthening effectiveness, of already existing cracks when a beam is shear strengthened with NSM CFRP laminates, some of the RC beams were pre-cracked prior to their strengthening. A detailed description of the carried out experimental research and a discussion of the obtained results are done in the present paper. |
