Abstract
In this paper, first of all, a finite element analysis of flexure concrete members strengthened with externally bonded FRP laminates is presented to make clear the mechanisms of shear stress transfer along FRP-concrete interface for different variables. Based on the results of numerical simulations, a test program is designed to verify the different reinforcing effects, the debonding and other failure behavior of FRP-strengthened beams involving the main parameters such as the number and the end placement of FRP laminates. Through the theoretical and experimental investigations, finally, an effective anchorage strategy is also proposed and demonstrated in the paper.
