Abstract

The most popular method to prevent corrosion of steel rebars and prestressing tendons is epoxy coating. This paper presents an alternative approach consisting in the combination of a fiber-reinforced-plastic (FRP) skin bonded to a steel wire core. The FRP skin is braided directly around the steel core, it can be made of various epoxy-impregnated fiber types, and it is fully-bonded to the core. The characteristics of hybrid reinforcement are such that both skin and core have a structural function. Experimental results are given to show the tensile characteristics of hybrid rods. The performance of reinforced concrete beams using conventional steel rebars, FRP rods, and hybrid rods is reported.
