Paper Title:
Fracture Parametric Study on Bond Behaviour between FRP Laminates and High Strength Concrete with Experiments
  Abstract

Recently, concrete structures deteriorating for various reasons and upgrading by bonding FRP using epoxy resins has attracted significant researches. Experimental studies in literates indicate that the anchorage between concrete and FRP laminates plays an important role in the reinforcing design. However, few and no special study has extended to high strength concrete. This research examines the bond behaviour between FRP laminates and high strength concrete. To obtain the bond strength and regulation of debonding propagation, a simple face shear type bond test is conducted. With the explicit material and geometric descriptions and the fairly general boundary conditions, the interfacial fracture energy release rate, Gf of this test model which is then used to propose the prediction of the bond strength is derived. Comparison of this energy basis model in prediction of bond strength with the model of Chen & Teng which has a high accuracy in this area and results from this experiment demonstrates the derived prediction model as a feasible and effective measure in analyzing the bond behaviour between FRP and high strength concrete.
