In addition, in order to favour a box-like behaviour of the entire building, walking strips, at the inter-floor level, have been foreseen, realised through the application of ultra-high resistance galvanised steel fabrics UHTSS - S G SYSTEM (Steel Reinforced Grout) - immersed in an inorganic matrix of pure natural hydraulic lime. Finally, for the third deck on some internal wall faces and on the brick pillar, unidirectional and bidirectional carbon fibre fabrics - CFRP (Carbon Fiber Reinforced Poly er) - were used, embedded in an organic epoxy matrix, after regularising the surfaces with a inorganic matrix of pure natural hydraulic lime. All the above systems are certified in accordance with the Ministerial Guidelines issued by the MIT STC. These reinforcement methods allow for a general improvement in the mechanical characteristics of the masonry, both in terms of local crisis phenomena and the overall behaviour of the structure. © 2022 The Authors.
