Abstract:This research examines the bond behavior between fiber-reinforced polymer (FRP) laminates and concrete. To obtain the local bond stress versus slippage relationship, a double-face shear type bond test is conducted. The primary test variables are the types of fiber and concrete. The test results show that fiber stiffness influences both the bond strength and shape of stress distribution. The obtained local bond stress-slip relationships, however, are not influenced by the type of fiber. Only the maximum local bond stress increases as concrete compressive strength also increases. A new model representing the local bond stress versus slippage relationship is proposed using Popovics’s formula, which has been adapted to present the concrete compressive stress-strain relationship. A numerical analysis is performed to confirm the model, and experimental results are presented. The analytical results show a good agreement with the bond strength and strain distribution found in the experimental results.
