Strengthening of Masonry Wall Using Wire Mesh

The inherent weakness of masonry in tension has been repeatedly demonstrated in seismic events. The need to overcome seismic deficiency of unreinforced masonry (URM) panels has led to the development of structural walls with different reinforcement patterns. Confined masonry (CM), which consists of an URM masonry panel bordered with slender columns and beams, is one such alternative. Confining elements, tie columns and bond beams, are cast after the construction of the wall. These elements are usually constructed of reinforced concrete, although timber, reinforced masonry, and other materials have been used occasionally. RC frames with unreinforced masonry infill walls are common in developing countries with regions of high seismicity. Masonry is a complex material it is well known that masonry has a good performance when resisting and transmittingcompressive loads and a poor performance to resist tensile demands so the wire mesh is infilled in the wall in order to study the behavior of Infill masonry walls under cyclic loading by strengthening with wire mesh , Optimize the size and diameter of the mesh for maximum increase in shear strength and ductility , Anchorage of mesh to the columns , Study behaviour with openings and analyse the result of load bearing capacity and strength attain by the normal masonry wall and the wall infilled with the wire mesh.
