Mechanical Behavior for RC Beams Strengthened with Near-Surface-Mounted Bars Considering Effect of Secondary Loading

Abstract:

Compared with other strengthening methods, NSM FRP bars strengthening method has obvious advantages in bond property and fire prevention performance. In accordance with current experimental study and the theory of concrete beams strengthened in bending with FRP are introduced, and the effect of FRP bars strengthening quantity on failure modes of reinforcement beams and the initial load level influence on the ultimate bearing capacity are analyzed. It provides a basis for further research and application in China.
