Simulation on Bond Behavior of RC Beams Strengthened with FRP

Article Preview

Abstract:

The bond behavior on the FRP-concrete interface is a key factor to affect the behavior of members strengthened with FRP. In this paper, an analytical model to simulate the bond behavior on FRP-concrete interface between two adjacent cracks is derived; furthermore, the calculation method of the steel strain at the crack which is the key parameter in this model is given. Comparison between experimental result and theoretical calculation on FRP stain distribution in beam indicates that the analytical model can well predict the test results.
