behavior between concrete and FRP system. The numerical results, obtained by performing standard tests on plain concrete elements and an RC concrete beam both retrofitted with nano-enhanced FRP plate, are in good agreement with the experimental outcomes highlighting the good numerical capabilities of the proposed model to analyze such kinds of structures improved with the incorporation of nanomaterials.
