State-of-the-Art Review on Anti-Ram Bollards
Perimeter protection is an important physical protection approach for buildings and infrastructures, which is also regarded as the first line of protection. Vehicle borne improvised explosive devices (VBIED) have been recognized as a major design threat by many government agencies for years, since they have been so extensively used in past terrorist attacks against critical buildings and infrastructures. Preventing unauthorized vehicles from approaching a protected area with vehicle barriers installed in perimeter of the buildings and infrastructures would consequently reduce blast and debris threats. The history of test certification standard for vehicle barriers is briefly reviewed. The research achievements on anti-ram bollards, one type of vehicle barriers, in the fields of crash test, numerical simulation, and design theory are presented. The remaining problems and deficiencies of the research are pointed out and the corresponding proposals are put forward. Finally, some further research works on anti-ram bollards are proposed.
