Abstract
Based on the increasing demand of the self-interlocking stabilized earth blocks in masonry industry and history of the earthquake losses, research study on strengthening and retrofitting techniques is needed for this novel masonry material. Therefore, in this research study, a damaged dry stacked self-interlocking block masonry structure was retrofitted with ferrocement overlay and tested under quasi-static loading protocol. The performance of the tested structure before and after retrofitting are compared in terms of different seismic parameters including force–deformation, hysteresis loops, energy dissipation, lateral stiffness, displacement ductility, response modifications factors, and performance levels. It was found that the seismic capacity of the damaged dry stacked self-interlocking masonry structure was restored and enhanced.
