This paper focuses on the in-plane behaviour of rubble stone masonry with lime mortar strengthened with different solutions. The applied retrofit solutions are specific for historic masonry buildings, such as the injection of mortar and FRCM systems. The main experimental results obtained in terms of resistance, deformation capacity, deformed shapes, and dissipated energy are presented and compared with equivalent strengthening solutions in masonry walls from the literature.
This paper focuses on the in-plane behaviour of rubble stone masonry with lime mortar strengthened with different solutions. For that, 12 rubble stone masonry wall specimens, with construction features typical of ancient historic buildings of Southern Portugal and Mediterranean countries, were subjected to in-plane quasi-static cyclic tests. The applied retrofit solutions are specific for historic masonry buildings, such as the injection of mortar and FRCM systems, with glass and carbon meshes. The main experimental results obtained are presented through envelope curves, in terms of resistance, deformation capacity, and deformed shapes. Moreover, dissipated energy is also commented on. Horizontal drift results are compared and analysed together with the ones obtained in the literature for equivalent strengthening solutions in masonry walls.
