This report describes a series of tests that used an explosively-driven large-diameter shock tube to shatter an 8-ft x 8-ft brick wall, an 8-ft x 8-ft x 5-in reinforced concrete structural panel, an 8-ft x 8-ft x 4-in reinforced concrete spandrel panel, and an 8-ft x 8-ft clay tile roof using relatively low-pressure, long-duration blast loads. All four tests obtained power law size distributions with exponents between 0.80 and 1.07. The results are comparable to those obtained in earlier tests, including a test involving an 8-ft x 8-ft cinder block wall, and a test series involving small-scale simply-supported plates composed of glass, concrete, and masonry.
