Probability-based assessment of dam safety using combined risk analysis and reliability methods – application to hazards studies / Laurent Peyras in European journal of environmental and civil engineering, Vol. 16 N° 7 (Juillet 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 7 (Juillet 2012) . - pp. 795-817 Titre : Probability-based assessment of dam safety using combined risk analysis and reliability methods – application to hazards studies Type de document : texte imprimé Auteurs : Laurent Peyras, Auteur ; Claudio Carvajal, Auteur ; Huguette Felix, Auteur Année de publication : 2012 Article en page(s) : pp. 795-817 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Dam  Reliability  Risk  analysis  Security  Hazards  study Résumé : Dam safety assessment is a major challenge for engineers specialising in hydraulic works. It is now standardised in regulations providing for hazards studies using probability-based risk analysis procedures. Dam safety probability-based assessment includes two key scientific issues: the modelling of complex mechanisms that occur within the works, and a probability-based assessment of structural safety. This paper introduces a combined application of risk analysis and dam reliability methodologies. This combination required the completion of our work on the adaptation of risk analysis methods to dams, and on the probability-based modelling of strength and loading input data for a reliability-based analysis. These methodologies are then implemented as part of a hazards study on a roller-compacted-concrete gravity dam.
