ABSTRACT: The use of fully grouted Reinforced Masonry Shear Walls (RMSWs) has been growing in several areas around the world owing to their relative ease of construction. Although the walls can be detailed to possess a high level of in-plane ductility, they typically have very low out-of-plane ductility due to the standard masonry unit configuration and the mid-cell reinforcement bar placement. As a result, such walls might be vulnerable under out-of-plane loading induced by blast which hinders the robustness (one of the resilience attributes) of RMSW buildings under such loading conditions.
