Abstract

ABSTRACT

In this experimental study, six identical infill wall specimens (755mmx755mm) were constructed. Infill wall specimens having the same mortar ratios were divided into 3 groups, each group being consisted of 2 specimens. Two groups were strengthened by applying single layer and double layer of cementitious matrix-fabric (CMF) system on the surface of infill walls. The third group was prepared without any strengthening material, in order to be used as control specimens.
Diagonal tension tests for all groups were conducted in order to determine the contribution of CMF system to the strength and ductility of infill walls. Test results were evaluated considering experimental parameters such as shear stress, shearing strain, and modulus of rigidity. Results showed that CMF system considerably improved the experimental parameters for the infill walls.
