This report presents the results of blast load resistance testing of masonry walls that minimally meet applicable Unified Facilities Criteria UFC reinforcement requirements. The testing and analyses presented in this report involved partially-grouted 1 6-inch, 2 8-inch, and 3 insulated clay brick veneer cavity wall concrete masonry test panels. Three blast load experiments were conducted each experiment tested one each of the three test panel designs nine test panels total. The impulse loading to the panels varied significantly between each of the three experiments. Failure mechanism observations were made using interior and exterior high-speed videos that captured the response of each panel. A post-test forensic investigation was also conducted after each experiment to further explore and document the ultimate response of each test article. Dynamic deflections were captured and the responses were compared to blast analysis codes used for masonry design.
