The ultimate strength of R/C beams retrofitted in flexure by means of externally bonded fiber reinforced polymers (FRP) has attracted the attention of many researchers in the last decade. In this paper, a new definition of the design strength of the externally bonded FRP reinforcement is porposed for flexural plates, taking into account the ulimate anchorage force. In the first part of the paper the model is presented and discussed; in the second part, the proposed model is validated by comparison with a wide number of experimental results. The application to the available experimental tests shows the robustness of the method, which appears to be fully eligible as a design practice procedure.

Abstract

The ultimate strength of R/C beams retrofitted in flexure by means of externally bonded fiber reinforced polymers (FRP) has attracted the attention of many researchers in the last decade. In this paper, a new definition of the design strength of the externally bonded FRP reinforcement is porposed for flexural plates, taking into account the ulimate anchorage force. In the first part of the paper the model is presented and discussed; in the second part, the proposed model is validated by comparison with a wide number of experimental results. The application to the available experimental tests shows the robustness of the method, which appears to be fully eligible as a design practice procedure.
