Abstract: This paper presents experimental research on reinforced concrete (RC) beams with external flexural and flexural–shear strengthening by fibre reinforced polymer (FRP) sheets consisting of carbon FRP (CFRP) and glass FRP (GFRP). The work carried out has examined both the flexural and flexural–shear strengthening capacities of retrofitted RC beams and has indicated how different strengthening arrangements of CFRP and GFRP sheets affect behaviour of the RC beams strengthened. Research output shows that the flexural–shear strengthening arrangement is much more effective than the flexural one in enhancing the stiffness, the ultimate strength and hardening behaviour of the RC beam. In addition theoretical calculations are developed to estimate the bending and shear capacities of the beams tested, which are compared with the corresponding experimental results.

TL;DR: In this article, the authors assess some common design models for the prediction of the shear capacity of reinforced concrete (RC) elements with externally bonded FRP composites, based on a wide database collected from recent literature and mainly focused on the combination of the basic codes for RC structures (without strengthening) with current models for FRP shear strengthened structures.
Abstract: Shear strengthening of reinforced concrete (RC) elements with fibre reinforced polymer (FRP) composites is actually a research topic far to be completely solved. Existing shear strength models lead sometimes to overly non-conservative results and need to be validated with a sufficient number of experimental tests. The aim of this work is to assess some common design models for the prediction of the shear capacity of RC beams strengthened with externally bonded FRP composites. The research is based on a wide database collected from recent literature and is mainly focused on the combination of the basic codes for RC structures (without strengthening) with current models for FRP shear strengthened structures. The research significance of this work is due to the lack of information on the performance of the above models when combined with basic codes. Particular attention was dedicated on the consistency of the models for FRP strengthened structures with Eurocode 2 [12] , since it assumes a method based on the truss model with variable inclination of the compressed strut. Lastly, some improvements of the model proposed by Pellegrino and Modena [41] , which takes into account the interaction between steel and FRP contributions to the shear capacity, are proposed.
