An Innovative Energy-Absorbing Anti-Terrorism Crash Barrier for Homeland Security

August 11, 2010 By  Marc. Caspe, Jun Ji, Lin Shen, and Qian Wang Abstract   Anti-terrorism physical barrier techniques and applications have become highly desired to protect critical facilities and human lives in recent years. Based on in-depth review and practices, the systemic criteria are proposed here for selection of security barriers specifically against terrorist attacks with truck-borne explosives.  Motivated from the survey and evaluation of typical perimeter security systems, a highly secured Surface Barrier and associated technologies developed recently are presented in details. In contrast to most conventional barriers with a fixed base, the proposed new Surface Barrier technology employs an innovative “calibrated” energy-dissipation concept to decelerate a crashing vehicle gradually instead of relying on rigid impact. The impact force transferred to the base is controlled to such a low level that deep or massive foundations are not needed...
