The primary objective is to present a general review on effect of infill strength and stiffness in the seismic analysis of open ground storey building. The typical multi-storey construction comprises reinforced concrete (RC) frames with brick masonry infills. Presence of unreinforced infill walls in the frames alters the behaviour of the building under lateral loads. It is seen that the masonry infills contribute significant lateral stiffness, strength, overall ductility and energy dissipation capacity. However, in practice, the infill stiffness is commonly ignored in frame analysis. Infill behaves like compression strut between column and beam and compression forces are transferred from one node to another. The model uses an equivalent diagonal method to calculate the infill walls, as recommended in the literature. In this study, contribution of infill walls to stiffness of the structure was analyzed in reinforced concrete framed building.
