Abstract: Pattern recognition techniques have been successfully employed in a wide variety of fields, such as geophysical exploration, medical diagnosis, radar tracking, and earthquake structural damage classification. To date, two investigations have been attempted in the explosive effects field: one identifying the explosive source based upon ground motion records and the second investigating the phenomenon of ground spall. This paper seeks to describe the utility of pattern recognition methods to help distinguish structural failure modes and also detail the difficulties inherent in a problem of this type. The problem involves the examination of dynamic response and failure of shallow-buried reinforced concrete box structures subjected to impulsive pressures.
