How to design buildings/architecture resistant from Bomb Attack
August 13, 2009
Bomb attack often, or even always possible, making the building as a target. Of course with the intent to kill dangerous as many of the target building. All the target of terrorism attacks, the building is in the public commercial plateau visitors. As a result, are very fatal, the victim lives and injured. How to design buildings/architecture that respond to?
Response in the form of design efforts is minimizing the possibility of building a targeted bomb attack and reduce the impact of the damage and danger to the result of the explosion. Design your own can not prevent the building became a target of attacks. Design is a form of passive defense. United States, especially since the attack of 9 / 11, has set the standard anti terrorism on the federal building which is considered the main target of the terrorist attacks. Weight or standard that is applied is adjusted to the federal building in sensitivity. Standard anti terrorism is an absolute requirement federal building. It seems this is not possible, considering the extent of coverage and cost must be paid for this. Moreover, in the case of the attack came from the last explosion in the building and not have to do on the design to truly prevent the explosive materials into the building with the perpetrators. There are a few things that can be applied simultaneously and can be a design consideration for the parties concerned.
First is the distance free and open space around the building.
Free distance is the distance between the building with minimal road and parking vehicles. Thus, the building has a buffer zone to minimize the attack of the vehicle. The placement of service areas, such as garbage, must also be considered against the distance.
Almost every building requires a certain area down-passenger ride (drop off) and goods loading and unloading area (loading Dock). If the area is absolutely must touch directly with the building, would not want to review the vehicle will enter this area. Direct access to the building must also be a place where parking restrictions. Open space around the building are intended to avoid or minimize the existence of objects that can be used as a hide bombs. The object is and can be a landscape feature, mechanical equipment, electrical support buildings, and trash.
Second, prevent the collapse of the structure
Structure of the building, especially for buildings more than three-floor, designed so that failure occurs when the structure of the area due to a bomb explosion will not spread to other parts of the structure. Thus, the total failure of the structure of the entire building can be avoided.
Third, avoid making the building occupant in the form of cantilever.
Bomb explosion in the style to give a lift to the cantilever ultimately can lead to fatal damage to the building.
Fourth Order to strengthen the exterior, such as doors, windows, curtain wall, and glass.
In the explosion of a bomb, which often become a danger for human is part of building the float due to pressure explosion. Door and window frames can be detached and become a projectile that is very dangerous. They also shatter glass float. Order-order exterior can not be strengthened so that when the explosion occurred. Glass can be coated a layer of special glass to keep bills, does not fly. Another way is more economical to install can be done with special curtains on the back window / glass holding the glass so that the fraction does not fly into the building. Interior furniture can also become a projectile when the explosion occurred. However, almost no one can do to minimize the impact of the danger of furniture / interior when the explosion occurred in the building.
Fifth is to secure access to the building through the service area.
Access to the building, such as roofing, elevator machine room, and enter the air, must be secured to prevent. Once again, the design can not prevent the building became a target of terrorist bomb-shaped. Can do is minimize the impact when the attack. Applied the above steps require significant costs. However, considering the already frequent bomb attacks by terrorists in Indonesia, it’s good the owners of buildings, whether existing or to be constructed, begin thinking anti terrorism factors in building design.
