This research features the bond behavior between fiber sheet and concrete. To obtain the local bond stress versus slippage relationship, doubleface shear test is conducted. The test variables are mainly the types of fiber and concrete. The test results show that sheet stiffness influences both of bond strength and shape of stress distribution. However, the obtained local bond stress-slippage relationships are not influenced by types of fiber sheet. Only the maximum local bond stress has an increment as concrete compressive strength also increases. A new model representing the relationship is proposed using Popovics formula, which is adapted to present the concrete compressive stress-strain relation. A numerical analysis is performed to confirm the model with experimental results. The analytical results show a good agreement in bond strength and strain distribution with experimental results.
