- Description
- An explosive field trial has been conducted in Australia that measured the free-field blast loading caused by C-4 (military standard) plastic explosives. The results have revealed a high level of variability of peak incident pressure, impulse and time of positive phase duration for repeatable tests where variability would be expected to be a minimum. The accuracy of predictive blast load models (model error) was also assessed. A probabilistic blast load model is developed that captures these observed variabilities. The probabilistic model considers variability and/or uncertainty of explosive mass, stand-off distance, air temperature, air pressure, inherent variabilities and model error. This type of statistical and probabilistic analysis is essential for structural reliability analysis of structures subject to explosive blast loading where load variability is an important contributor to damage and safety risks. It will also be useful for design where for a specific explosive scenario it is possible to calculate an upper bound (or characteristic) design load; for example, a design (95th percentile) blast load with a 0.95 probability of non-exceedance. In addition, it will allow the conservatism (if any) of existing deterministic design load tools such as ConWep and TM5-1300 to be assessed.
