A new masonry system built of semi interlocking masonry (SIM) has been developed to improve the seismic behaviour of framed structures with masonry infill panels. SIM panels are built with masonry units capable of relative sliding in-plane of a panel but locked against relative movement out-of-plane. SIM has reduced in-plane stiffness and increased frictional energy dissipation capacity compared with traditional masonry infill panels. In-plane cyclic tests have been performed on two different types of framed masonry systems: reinforced concrete (RC) frame with a prototype SIM panel and steel frame with a topologically SIM panel. This paper presents a comparative study of these two different types of framed masonry systems in response to in-plane cyclic displacement. The hysteretic behaviour and the energy dissipation are compared.
