The Debris Cannon Laboratory is a joint venture between the Department of Civil, Construction, and Environmental Engineering and the Alabama Center for Insurance Information and Research. The cannon can independently or simultaneously launch debris from each of the four barrels. Each barrel can be independently loaded with unique material, aimed, and fired at different speeds. The University of Alabama commissioned a four-barrel debris cannon to simulate and study building envelope damage caused by wind-borne debris. The ability to launch four projectiles allows researchers to strike a structure at four different critical locations either simultaneously or in succession.
