Abstract
A survey was performed to find in the literature theoretical models suitable to the description of the triaxial creep behaviour of plain concrete at high stresses. The considered models are based on the theory of elasto-viscoplasticity with damage and are mainly addressed to the domain of geotechnics. Application of these models to the simulation of experiments turned out to be satisfactory on the whole, although several features of the creep behaviour of the material are not reproduced. The suggestions given by this preliminary work will be taken into account in the development of a future model specifically conceived for concrete.
Résumé
On a conduit une recherche bibliographique pour répérer des modèles mathématiques capables de décrire le comportement de fluage du béton ordinaire soumis à des contraintes triaxiales prolongées de haute intensité. Les modèles considérés se basent sur la théorie de l'élasto-viscoplasticité avec endommagement, et sont conçus principalement pour des matériaux géotechniques. Leur application à la simulation des expériences s'est avérée satisfaisante, bien que plusieurs aspects du comportement de fluage du matériau ne soient pas reproduits. Les indications fournies par ce travail préliminaire seront prises en compte dans le développement d'un modèle conçu spécifiquement pour le béton.
