Modelli di arco rinforzati con materiali compositi

Assessment of the effects of the application of advanced materials and new technologies on traditional structures has assumed a major relevance within the ongoing debate on the preservation of historical buildings. In the paper, some results of a wide experimental analysis carried out at the Laboratory of Dipartimento di Costruzioni of the University of Florence are reported. The results regard mechanical tests on scale models of masonry arches reinforced with CFRP (Carbon Fiber Reinforced Polymer) and GFRCM (Glass Fiber Reinforced Cement Matrix) strips, bonded at the intrados or extrados with distinct configurations. The results of the experimental trials allowed to evaluate the impact of different reinforcement configurations on the strength of masonry arches and then to deduce considerations on sizing criteria for the CFRP strengthening of traditional masonry structures.
