Surface Barrier Technology:
Functionally Attractive, DOS K-12 Certified Perimeter Security Barriers

KKCS and its Team of security experts, is about to take bids for a Surface Barrier (SB) Security System made of decorative reinforced concrete street furniture. SB technology provides a physical barrier for gradually decelerating terrorists attacking with truck-borne explosives. Design impact forces from a Ford F800 truck weighing 15,000 pounds and traveling at over 50 mph has been stopped in less than two feet.

Sir Isaac Newton’s third law of motion teaches that a vehicle’s mass times its change in velocity can be successfully brought to rest at a zero velocity if a relatively constant deceleration force can be exerted for sufficient duration of time without failure. In every case the terrorist controls the chosen value of a truck’s Momentum; hence we can only defend by taking proactive control of the deceleration force’s Impulse Reaction.

Energy dissipation can best be accomplished by calibrating the deceleration force to gradually stop the attacking truck. By exerting a relatively constant “calibrated force,” energy-dissipaters can stop a terrorist vehicle’s explosive bearing truck bed at a secure perimeter from an attacked building, as determined by KKCS’ advanced analytic technology for protection of both life and property.

Crash validation of prototype SB performance is at DHS’ TRL Level 8+ for securing surface perimeters of buildings as well as any other crucial facilities, utilizing SB technology. SB technology is fully certified to meet both the State Department’s K-12 rating as well as ASTM F 2656-07 (M50) standards. Both certifications require preventing a 15,000lb Ford F-800 truck from breaching any security perimeter at 50mph, first with concentric impact and then with eccentric impact.

In addition, the SB is compatible with any landscape architecture desired when cast as concrete benches, planters, bike racks, parking meters, lamp posts, etc. to beautify any desired cityscape design. All shop-precast concrete will be environmentally friendly, with additives that reduce cement use by more than 50 percent.

Many buildings and bridges have limited space between heavily loaded structural columns and an adjacent roadway. Hence the SB security system should be placed as close to the roadway curb as possible, keeping any explosive detonation as far from the structural columns as possible to permit blast overpressure decay. By utilizing low cost and visually attractive benches combined with colorful planters or bicycle racks adjacent to the curbside of roadways. Cityscapes can be beautified and protected.

Existing slab-on-grade sidewalk diaphragms can serve as horizontal concrete restraints and deep-seated soil anchors can provide vertical restraints. SB security systems thereby attain a uniquely resilient security level. High tech impact and blast analyses utilizing ABAQUS or LS-DYNA for performance simulations, can account for both of impact forces as well as perimeter incursion by catapulting explosives from the truck bed.
