Abstract(s)The flexural behavior of RC beams strengthened with prestressed near-surface-mounted (NSM) carbon-fiber-reinforced-polymer (CFRP) laminate was investigated in this paper. For this purpose, four RC beams were tested under monotonic four-point loading. One beam was kept un-strengthened, as a control beam, and another one was strengthened with a non-prestressed NSM CFRP laminate. The remaining beams were strengthened with NSM CFRP laminates prestressed at 20% and 40% of its ultimate tensile strength. The prestressed NSM CFRP laminate technique provided a significant increment of the load carrying capacity for deflection levels corresponding to serviceability and ultimate limit states. A numerical strategy was also employed to simulate the flexural behavior of the tested RC beams. The experimental and numerical researches are described and the relevant results are presented and discussed.
