Retrofitting Masonry Vaults with Basalt Textile Reinforced Mortar
Due to their slenderness, masonry vaults are particularly vulnerable against unsymmetrical service loads, support displacements and seismic actions. Retrofitting works are therefore needed in numerous existing structures to ensure an adequate safety level according to current standard codes. This paper describes an experimental investigation carried out in the laboratory on two full-scale vault mock-ups. One of them was tested unreinforced, while the other one was strengthened with a basalt mesh applied at the extrados with lime-based mortar. Aiming at reproducing the actual condition of brick vaults in historic constructions, the specimens were provided with buttresses and filling. The load was applied over the filling at 1/3 of the span and increased cyclically up to failure. The tests provided the increase in load-carrying capacity attained with the basalt TRM reinforcement and the modification of the associated failure mode.
