The out-of-plane response of masonry walls strengthened with textile-reinforced mortar (TRM) is experimentally investigated in this work. Medium-scale three-point bending tests were carried out on 18 specimens comprising a set of 9 single-wythe and 9 double-wythe brick masonry walls. Key investigated parameters involved the textile reinforcement ratio, the textile material, the coating of the textile reinforcement with epoxy resin, and the wall thickness. Experimental results suggest that TRM significantly increase the load bearing capacity of masonry walls. The amount of reinforcement utilised affects both the strength and deformation characteristics of the corresponding specimens, while it may alter the failure mode. Resin coating on the textile is found to be beneficial for the performance of the TRM overlays.

The effectiveness of the textile reinforced mortar (TRM) strenghtening technique on clay brick masonry arches is investigated. Eight half-scaled specimens were subjected to static monotonic loading applied at the quarter length of the span until failure. Experimental parameters comprised the number of TRM layers, the textile fibre material, and the strengthening layout, i.e., application in either the intrados or the extrados. The experimental results are discussed in terms of the resulting failure mechanisms and conclusions are drawn with regards to the strength and deformability achieved through each strengthening strategy.
