D.5.3
Evaluation of Blast Damage to Structures. A federal installation or other target of
terrorists can contain a wide variety of construction types. The categories of wood, masonry,
reinforced concrete, and steel have been chosen to illustrate the range of damage possible. These
may serve as a rough guide when like construction is found. A methodology has been developed
to use pressure impulse curves to estimate damage. This work is documented in the "Facility
Component Explosive Damage Assessment Program". A computer program was developed
using Explosive Risk and Structural Damage Assessment Code (ERASDAC), Blast Damage
Assessment Model (BDAM), and the Facility and Component Explosive Damage Assessment
Program (FACEDAP).
Component damage and total target damage is related to weapon yield and range as a
percentage of economic loss. The size of the target is a factor in determining total target
damage. The percentage of loss is described qualitatively and in terms of survivability (e.g.,
reusability and repairability of the target). Although the damage to contents is not specifically
addressed, the target damage description may be adequate for a person with knowledge of the
contents and operational mission to determine the approximate damage.
