Noret, Auteur ; G. Prod'homme, Auteur ; T. Yalamas, Auteur Année de publication : 2012 Article en page(s) : pp. 998-1022 Note générale : Génie Civil Langues : Français (fre) Mots-clés : Domino effect Blast Impact Atmospheric tank Reliability sensitivity analysis Résumé : The occurrence of a chain reaction from blast on atmospheric storage tanks in oil and chemical facilities is hard to predict. The current French practice for SEVESO facilities ignores projectiles and assumes a critical peak overpressure value observed from accident data. This method could lead to conservative or dangerous assessments. This study presents various simple mechanical models to facilitate quick effective assessment of risk analysis, the results of which are compared with the current practice. The damage modes are based on experience of the most recent accidents in France. Uncertainty propagation methods are used in order to evaluate the sensitivity and the failure probability of global tank models for a selection of overpressure signatures. The current work makes use of these evaluations to demonstrate the importance of a dynamic analysis to study domino effects in accidents.
