Abstract: Masonry infill walls are globally used in RC frame including many developing countries. In the design, the properties of masonry infills are not generally taken into account and are considered as non-structural elements. Only the dead weight of the infill is considered in design while its effects on structural strength, stiffness and ductility is neglected, which may ultimately lead to an unsafe design. During lateral loading, Infills combined with the RC frame structures, increases the strength and stiffness of structures as compared to bare frame. In bounding frame, infill walls act as compression strut. Compression forces produced in the infill wall, moves from one node to the other. After providing openings in infill wall, the lateral loads resistance decreases and ultimately adds in reduction of structural strength and stiffness. This Paper reproduces information about, how masonry infill RC frames (with and without openings), can resist applied lateral forces. The previous studies summarized that the infilled walls bounding with RC frames increases the lateral stiffness, strength and reduce deflection while the RC frame having openings has properties opposite to it..
