EXAMPLES FOR PROTECTION AGAINST TERRORIST VEHICLE BOMBS
Scope. This appendix contains examples for determining the design of vehicle barrier
systems. The information contained herein is intended for guidance only.
Means, R.S., "Building Construction Cost Data," 55th Edition, 1997.
The definitions in Section 3 of this handbook apply to this appendix.
Example 1. Building 827 must be protected against a terrorist vehicle bomb. The
structure is a single-story, reinforced-concrete building. The following factors apply:
a) The tolerable level of damage to the building is minimal.
b) Some injury from debris is anticipated, but serious injury or death must be
avoided, if possible.
c) The design threat has been established as a vehicle with a gross weight of 15,000
pounds (6,818 kg), including 1,000 pounds (454 kg) of explosives traveling at 50 mph (80 kph).
This combination of vehicle size and speed will develop 1,253 ft-lbf (173 kgf-m) of energy on
Referring to Figure B-1, the line of approach is a perimeter road on the north and
west sides of the building. Perimeter static barriers and a movable barrier on the west entrance to
the facility will be required. A candidate active vehicle barrier system might be the Delta
TT207, described in Table 5 of Section 8. For the perimeter fence, a candidate passive barrier
could be the bollard system, shown in Figure 25 of Section 8.
