A Bayesian approach to estimate material properties from global statistical data / Benjamin Richard in European journal of environmental and civil engineering, Vol. 16 N° 3-4 (Mars/Avril 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 3-4 (Mars/Avril 2012) . - pp. 460-470 Titre : A Bayesian approach to estimate material properties from global statistical data Type de document : texte imprimé Auteurs : Benjamin Richard, Auteur ; Lucas Adelaide, Auteur ; Christian Cremonab, Auteur Année de publication : 2012 Article en page(s) : pp. 460-470 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Bayesian  networks  Updating  Damage  mechanics  Finite  elements  Modelling Résumé : This paper is devoted to presenting an updated approach based on the use of Bayesian networks. This methodology aims to update the statistical parameters related to a mechanical model thanks to experimental data. The proposed updating process has been applied to engineering problems. The results show that the proposed approach could be used to estimate the material parameters of a given structure and avoids carrying out destructive tests on site.

A simplified numerical approach of global behaviour of RC beams degraded by corrosion / Lucas Adelaide in European journal of environmental and civil engineering, Vol. 16 N° 3-4 (Mars/Avril 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 3-4 (Mars/Avril 2012) . - pp. 414-439 Titre : A simplified numerical approach of global behaviour of RC beams degraded by corrosion Type de document : texte imprimé Auteurs : Lucas Adelaide, Auteur ; Benjamin Richard, Auteur ; Frédéric Ragueneau, Auteur Année de publication : 2012 Article en page(s) : pp. 414-439 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Steel/concrete  interface  Modelling  Multifiber  Corrosion  Reinforced  concrete Résumé : One of major causes responsible for the performance loss of reinforced concrete structures is the corrosion phenomenon. Thereby, taking into account the local effects of the steel/concrete interface is of primary importance to predict properly the response of corroded reinforced concrete structures. A multifiber-based model including the steel/concrete interface is proposed. This interface model allows taking into consideration the bond strength variation due to corrosion. Such an approach leads to reasonable computational costs which a powerful feature of the model. A numerical study of beams already studied in the French project « benchmark des poutres de la Rance » is proposed in order to show the efficiency and reliability of the proposed model.
