Frequent earthquake hits and sudden structural collapses worldwide have persistently proven the vulnerability of Unreinforced Masonry (URM) Walls exposed to earthquakes. URM Walls experience in-plane and out-of-plane failures when the structural supports undergo seismic movements. Despite being efficient to withstand high compressive loads, masonry walls exhibit unanticipated collapses due to their brittle nature under the flexural and shear forces. Consequently, the development of strengthening techniques to impart ductility and provide sufficient warning before collapse has been the major focus of masonry research. Traditional techniques are less preferred because of their potential disadvantages. Modern strengthening methods utilizing Fiber Reinforced Polymers (FRP), Welded Wire Meshes (WWM), and textiles, have been proposed by various researchers around the world. This paper will discuss the Diagonal Shear behaviour of single wythe URM wallets of dimensions 480 mm × 480 mm × 110 mm strengthened with 300kN/m uniaxial and 30kN/m biaxial geo-grids. The study revealed that the load-bearing capacity, ductility, and the energy dissipated by the walls have significantly multiplied with textile strengthening.
