RESEARCH ON THE BEHAVIOR OF METAL CONSTRUCTIONS UNDER THE ACTION OF EXPLOSIONS
Abstract
The explosions produced in industrial/chemical facilities, such as hazardous material storage facilities, are events with low probability but high destructive potential. When occurring in a densely populated area, such explosions can lead to extensive damage of nearby buildings or infrastructures, resulting in high economic costs and human injuries and fatalities. The explosions may be the result of an accident but may also be intentional. As the pressure released by the external explosions decreases exponentially with the distance to the target, increasing the stand-off distance is one of the most effective ways to mitigate the effects against structures. In addition, the local resistance of the facade elements must be increased to prevent or limit the spread of damage. Even though these issues are well known and understood, there are relatively few provisions in the current European practice. The destructive effect of the high velocity debris projected by the explosion should also require attention, as they can cause severe harm to people. The study presented in the paper investigates the capacity of light steel-based building facades to resist the effects of near field blasts. The experimental results showed the ultimate capacity of the wall panels is strongly dependent on the initial design conditions and panel-to-structure fastening solution.
