This report presents the results of a study to develop a computer model to assist in analyzing the effects of vehicle attacks. The physical security program of the Department of State (DOS) has five tiers, the first of which is perimeter protection. Perimeter barriers are structures designed to protect an embassy by preventing an attacking vehicle from penetrating the embassy compound. The current designs are costly and there are also U.S. Diplomatic missions which can not use the current barrier designs. Each design change means the new barrier must undergo full-scale crash tests which are costly. The cost quickly escalates when a barrier does not pass the first test and must be redesigned and tested again.
The goal of this computer program is to evaluate the adequacy of potential barrier designs and thereby reduce full scale impact tests. Furthermore this program should allow the DOS personnel to identify the necessary size of the barrier and to eliminate the need to excessively over build. It should also be capable of exploring variations of the barriers which may fit currently unmet needs. The fundamental approach to embassy security is to develop the appropriate standards and enforce them throughout the world. One step in enforcing these standards is having a reliable and inexpensive means of testing barriers to establish if they are meeting the standards.
New standards have been proposed to increase the strength requirements for cab car end structures and impose further requirements on their ability to ...
Near-fault earthquakes can have major effects on transportation systems due to the structural damage they impose on bridges. Therefore, it is imperati...
