Cyclic shear-compression testing of brick masonry walls repaired and retrofitted with basalt textile reinforced mortar

This paper reports an experimental programme on masonry walls composed of handmade solid clay brick and hydraulic lime mortar. Reversed cyclic shear compression tests were carried out the in three different configurations: unreinforced, repaired retrofitted, just retrofitted. Damaged retrofitted with Basalt Textile Reinforced Mortar (B-TRM) tested again to investigate recovery strength, stiffness improvement drift capacity. The repair consisted filling open cracks replacing damaged bricks by following so-called “scuci-cuci” technique. configuration externally bonded B-TRM undamaged walls. system comprised continuous bidirectional grids basalt fibre embedded mortar both surfaces results showed suitability proposed solutions for seismic retrofit post-earthquake existing buildings. research highlighted capacity technique reinforce effectiveness investigated increasing resistance, ductility, energy dissipation unreinforced masonry. In addition, allowed a better understanding behaviour subjected horizontal displacement terms failure mechanism capacities.
