Development of earthquake resistant masonry


Dr Yuri Totoev

Project Description

Masonry walls are often used in multi-storey framed structures as infill panels. A new masonry system has been developed to improve the seismic behaviour of framed structures with masonry infill panels. It is called semi interlocking masonry (SIM). In this system dry-stack infill panels are built with masonry units capable of relative sliding in-plane of a panel. SIM panels have reduced in-plane stiffness and increased frictional energy dissipation capacity compared with traditional masonry infill panels. Under seismic loads these panels do not detrimentally interfere with the natural frame vibration but rather positively contribute to earthquake resistance mainly by increasing damping.
