The interaction of masonry infill with RC frame structures is complex and depends on various parameters such as strength of masonry infill, mortar, concrete, aspect ratio of the infill, openings in infill, and distribution of infill in plan and elevation. Though the number of bays and storeys affect the interaction of the infill and RC frame, earlier experimental research predominantly consisted of a one-storey one-bay frame. Limited research is available due to the difficulties in experimentation, cost and testing facility. Open ground storey (pilotis) structures are recommended to be avoided in high seismic zones because of the formation of soft storey mechanism and sudden failure of the ground storey. This numerical study aims at understanding the behaviour of fully infilled RC masonry frame in comparison with OGS frame. The parameters include aspect ratio (height to length ratio), number of bays and number of storeys. Interestingly it has been observed from the results that the failure is at the ground storey irrespective of infilled ground storey or OGS.
