Abstract
In this paper, several FRP-reinforced concrete beams are modelled using a recently developed one-dimensional two-node layered composite beam element which accounts for the bond-slip between reinforcing bars and the surrounding concrete. Effect of different surfaces of FRP reinforcing bars on the structural response of FRP-reinforced concrete beams with bond-slip effect is also investigated. It is found that the type of rebar surface has a significant influence on bond strength and structural behaviour, and that the grain-covered surface provides the best bond between the FRP rebars and concrete, the smooth surface the worst, and FRP rebars with ribbed and braided surfaces perform similarly.
