Specifically, the preliminary outcomes of the proposed experimental program will be presented. Simultaneously, a Finite Element (FE) model was calibrated in order to interpret the data and gain a better understand the phenomenology. The results obtained can provide useful hints for the design of this strengthening intervention. XX ANIDIS Conference Experimental and numerical study on masonry barrel vault strengthened through CRM system: preliminary results Marielisa Di Leto a, *, Filippo Campisi a , Giuseppe Rusticano a Calogero Cucchiara a , Lidia La Mendola a , Diego Antonio Trapani a a Department of Engineering, University of Palermo, Viale delle Scienze, Palermo, 90128, Italy Abstract Masonry vaults are widespread in the ancient built environment; they frequently provide a load-bearing purpose and can have numerous variables that influence structural behaviour, e.g., shape, materials, and boundary conditions. These structures may require strengthening interventions to increase load-bearing capacity and minimise vulnerability. In the presence of masonry substrate, intervention approaches based on inorganic matrix composite materials are preferred. Despite their growing popularity, there are just a few experimental campaigns in the literature that employ these composite materials to reinforce curved surfaces.
