The document discusses reinforced hollow concrete block masonry (RHCBM) as a construction method that can effectively resist seismic forces. RHCBM involves reinforcing hollow concrete blocks with vertical and horizontal steel reinforcement. It provides benefits like increased strength, ductility, cost-effectiveness, and faster construction compared to other methods. For existing non-engineered masonry structures, retrofitting techniques like grouting and wire meshing can be used to enhance earthquake resistance. Experimental results show RHCBM panels have higher ultimate load capacity and displacement ductility than conventional masonry.
