Özet
Past destructive earthquakes have clearly demonstrated that masonry structures can cause significant loss of life and property. The fact that a substantial portion of the existing masonry building stock was constructed without adequate engineering services, together with the inherently brittle behavior of masonry units and mortar, constitutes one of the primary reasons for their inadequate seismic performance. In particular, their limited deformation and energy dissipation capacities under repeated and cyclic loading may lead to the development of in-plane and out-of-plane damage in masonry walls and, at advanced damage levels, to partial or complete collapse. Therefore, the development of strengthening techniques that are structurally effective, environmentally sustainable, and practically applicable in the field is of considerable importance. Fiber-reinforced polymer (FRP) systems, including carbon- and basalt-fiber-reinforced polymers (CFRP and BFRP), as well as textile-reinforced mortar (TRM) systems composed of various fiber and matrix combinations, are widely used for the strengthening of masonry structures. Although these systems can provide significant improvements in load-carrying capacity, stiffness, and ductility, they may also involve certain environmental and economic limitations depending on the constituent materials employed. In particular, the use of synthetic resins, relatively high costs, and associated environmental impacts of epoxy-bonded FRP systems are regarded as notable disadvantages. In this context, strengthening systems incorporating natural fibers derived from renewable resources have increasingly been investigated in recent years as sustainable alternatives due to their lower environmental impact and economic potential.
