Blast Resistance of Fully Grouted Reinforced Concrete Masonry Veneer Walls
2014
AbstractThis paper describes the full-scale experimental evaluation of the out-of-plane flexural response of fully grouted RC masonry walls subjected to uniform static pressure and to dynamic pressure resulting from an explosion. The investigation was performed as part of a larger effort to improve the design methodologies for reinforced masonry subjected to blast loading. The masonry walls were non-load-bearing and vertically spanning, which represents a significant amount of common construction in the United States. Both single-wythe and veneer wall sections were evaluated. Two types of concrete masonry units were used, i.e., conventional and A-block concrete masonry units. The results of the program provide a better understanding of the ultimate dynamic capacities and ductility of reinforced masonry walls—both single-wythe and veneer walls—which will ultimately help engineers produce designs that are safer and more economical.
