Strengthening of brick masonry wallette by polyester geo-fabric reinforced cementitious matrix

Abstract

Abstract Brick masonry units along with masonry mortar are commonly adopted as infill in reinforced concrete framed structures. The property of brick and brick panels varies from one region to other region. A conventional masonry exhibits poor performance in terms of shear and tensile property under lateral loads. Several researchers worked on strengthening of masonry infill (MI) and proposed different strengthening techniques to overcome the effect of shear and Tension. Recently, the most convenient and effective technique developed to reinforce conventional masonry infill by fabric with help of cementitious matrix is called Fabric Reinforced Cementitious Matrix (FRCM). In this present study the strengthening of brick masonry elements are strengthened with polyester geo-fabrics with inorganic cement binder matrix on the both faces of masonry assemblages to study the mechanical properties under different experimental investigations. The results showed that 15% enhancement in compressive strength and 51% enhancement in shear strength compared with conventional unreinforced masonry wallettes.
