The prototype measured 3.31 x 4.19 m(2) by 2.15 m high and had a wall thickness of 230 mm. The masonry was composed of 230 x 110 x 50 mm(3) solid clay bricks with approximately 10 mm-thick mortar joints arranged in English bond. The tests were aimed at evaluating the effectiveness of cement-based reinforcing materials (Textile Reinforced Mortar) applied to weak masonry substrates severely damaged by horizontal loads such as those induced by a seismic event. The tests were carried out in three phases: (i) testing of the as-built structure, (ii) application of one external layer of TRM to restore the masonry's original load-bearing capacity and then (iii) testing the TRM-strengthened structure. Dynamic behaviour was monitored by both traditional and fibre optic sensors (FO), including 28 Linear Variable Displacement Transducers (LVDTs) and 3 long-gauge optical sensors. Strengthening effectiveness was evaluated by several parameters: hysteretic curves, strength degradation, computed cumulative energy dissipation and cracking mechanisms. TRM reinforcement was shown to significantly extend the load-bearing and displacement capacity of the masonry prototype, reducing seismic-induced damage applied by pseudodynamic excitation, although it had a limited effect on cumulative energy dissipation.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Textile Reinforced Mortar (TRM)In-Scale Masonry StructureExperimental Pseudo Dynamic TestsSeismic PerformanceINGENIERIA DE LA CONSTRUCCIONArtículo10.1016/j.conbuildmat.2020.118532Abierto09.- Desarrollar infraestructuras resilientes, promover la industrialización inclusiva y sostenible, y fomentar la innovación
