Abstract

The bond between reinforcing bars and the surrounding concrete is one of the dominant mechanisms affecting the structural behavior of fiber-reinforced polymer (FRP)-reinforced concrete structures. In this chapter, the experimental and numerical studies on the bond mechanism between FRP rebars and concrete in FRP-reinforced concrete beams are presented. Concrete beams reinforced with three types of FRP rebars with different rebar surfaces were tested under four-point bending loads to investigate the effects of types and surface conditions of FRP rebars on the bond–slip behavior ...
