“…The use of fiber-reinforced polymer with organic (epoxy-resin-based) composites for applications in masonry structures is discouraged because of the drawbacks pertaining to diminished performance at elevated temperatures, requirements of protective coatings, degradation of mechanical properties after continuous exposure to certain environmental surroundings [5], lack of Buildings 2023, 13,1495 2 of 21 compatibility between the resin and masonry surface, production of toxic gases associated with the use of FRP resin in epoxy application and relatively higher level of care and supervision required in application [6,7]. To overcome these drawbacks, environmentally friendly, thermal-resistant, non-corrosive composite material is used to reinforce walls by replacing FRPs with geo-fabric materials [8][9][10], and results showed that these geo-fabrics help to increase the shear and flexural capacity [11,12].…”

The interfaces between masonry infill and reinforced concrete (MI-RC) frames are identified as the weakest regions under lateral loads. Hence, the behavior of such frames under lateral loads can be understood mainly through experimental investigations. The deformation demands induced by horizontal loads on RC frames with infill masonry walls change due to contact losses between the infill masonry and the RC frames. This can be controlled by providing proper reinforcements at the interfaces. In the present experimental investigation, three half-scaled models subjected to reversed cyclic lateral in-plane loads were tested. In detail, the specimens considered are the MI-RC frame model, an MI-RC frame with geo-fabric reinforcement at the interface and an MI-RC frame with geo-fabric reinforcement at interfaces with an open ground story. The models were subjected to reversed cyclic lateral in-plane loads, and the post-yield responses of the models with respect to stiffness degradation, drift, energy dissipation, ductility and failure mode have been discussed.
