Behavior of Cantilever RC Beam Support Strengthened with Near-Surface-Mounted FRP Bars
Several parameters, including typical loads, deflection, strains of steel bar and fiber- reinforced-polymer(FRP) bar under different sustained loading, were studied. The yield load and ultimate load of cantilever beams strengthened with near-surface-mounted(NSM) FRP bars are improved by 6.0%~15.2% and 55.7%~64.5% compared with non-strengthened beams, respectively. For strengthened beams,sustained loading can weaken the reinforced effect.The flexural behaviors of mounted beams were influenced by the lateral groove .
