Approximate Analysis and Design of Conventional Industrial Facilities Subjected to Bomb Blast Using the P-i Technique
Abstract
Efforts to characterize the response of complex structural systems to the intense transient loads generated by bomb blast can involve significant computational effort. Additionally, the practitioner must have a substantial amount of experience to interpret the results of these analyses. Unfortunately, when facilities are subject to terrorist attacks, sufficient time is often not available for detailed analysis. Southwest Research Institute (SwRI), under contract to the US Army Corps of Engineers at Omaha and the Naval Civil Engineering Laboratory at Port Hueneme, California, has been developing simplified procedures for the prediction of damage to conventional buildings generated by airblast transient loads. In these methods component damage is first calculated for each component in the building using pressure-impulse curves (P-i curves). The P-i curves relate non-dimensional terms calculated using the component geometry, material strength, material stiffness, and boundary condition, and the peak applied blast pressure and impulse, to component damage. The P-i curves were developed theoretically using an energy approach and then shifted, where necessary, to match measured damage data. The theoretical curves are shifted to match damage data in regions where the damage is overpredicted.
