Description
Summary:The vulnerability of masonry structures, especially when subjected to a changing of the load and boundary conditions, was evident since the antiqueness when the first interventions of reinforcement were designed. Lately, with the easy provision of innovative materials, the upgrade of the structural performance is often accomplished through the application of composite systems as FRP (fiber reinforced polymer) and TRM (textile reinforced mortar). In TRM systems, fibers having a high strength under tensions are embedded within an inorganic matrix. The wide range of materials (carbon, PBO, glass, basalt) that the industry put at disposal makes difficult a correct definition of the efficacy of such kind of reinforcement technique. Indeed, the literature showed the several failure typologies that can be encountered when a masonry element is reinforced with TRM. In the case of arches and vaults, the curvature itself complicates furthely a correct prediction. The paper wants to provide a reasonable way to model numerically curved masonry structures reinforced with TRM and explore the advantages and detriment of advanced simulation and simplified approaches.
