Investigation of Structural Damage and Repair Costs Resulting from an Accidental Explosive Detonation

摘要

The Department of Defense Explosives Safety Board publishes and maintains safety criteria applicable to DoD ammunition and explosives. If possible, this protection is provided by requiring a minimum separation distance between potential explosive donor and acceptor structures. At a military installation's boundary, the required separation distance is termed the Inhabited Building Distance (IBD). Beyond this distance, uncontrolled residential and commercial development must be accepted. According to the DoD Ammunition and Explosives Safety Standard, DoD 6055.9- STD, at IBD, '...Unstrengthened buildings can be expected to sustain damage up to about 5 percent of the replacement cost.' Unfortunately, cost data from recent explosive accidents, including the 1988 Pepcon explosion, indicate that actual damage costs at IBD separation distances will be significantly greater. In this paper, we will evaluate probable damages resulting from a hypothetical explosive detonation at a DoD installation. Our evaluation will be based upon the application of the IBD separation distance at the installation boundary and will consider both residential and commercial construction.
