- Description
- Explosive blasts in confined building spaces, such as lobbies or foyers, can amplify the blast loads. The paper uses ProsAir to estimate blast loads in a typical ground floor lobby of a commercial or government building. Monte-Carlo simulation is used to probabilistically model the effect that variability and uncertainty of charge mass and location, NEQ, height of burst, temperature, atmospheric pressure, and model error have on airblast variability. Human vulnerability due to the effects of pressure and impulse is a function of lung rupture, whole body displacement, or skull fracture (or the combination of the three). The analysis then calculates the probability of casualties due to the effects of pressure and impulse. The terrorist threats considered are improvised explosive devices (IEDs) ranging in mass from 5 kg (backpack bomb) to 20 kg (suitcase bomb) detonated in various locations inside the building. As expected, blast pressure and fatality risks are dependent on the type of facade glazing (e.g., vulnerable glazing allows venting of the blast), IED size and location. This probabilistic analysis allows decision-makers to be more aware of terrorism risks to building occupants, and how improved building design and security measures may ameliorate these risks.
