On mechanical degradation of reinforced concrete affected by alkali-silica reaction / A. Winnicki in Journal of engineering mechanics, Vol. 134 n°8 (Août 2008) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 134 n°8 (Août 2008) . - pp.611–627. Titre : On mechanical degradation of reinforced concrete affected by alkali-silica reaction Type de document : texte imprimé Auteurs : A. Winnicki, Auteur ; S. Pietruszczak, Auteur Année de publication : 2008 Article en page(s) : pp.611–627. Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Concrete  reinforced  Plasticity  Degradation  Mechanical  properties Résumé : In this paper a constitutive relation is developed for reinforced concrete subjected to a continuing alkali-silica reaction. The chemo-mechanical interaction is described within the framework of chemo-plasticity. The formulation invokes the assumption that the formation of expansive phases results in degradation of mechanical properties of the material. The approach employs a constitutive model for reinforced concrete, as recently developed by the writers. An extensive numerical analysis is conducted examining the effect of the reaction on mechanical characteristics in axial compression/tension for different reinforcement intensities. Some of the key results are compared with the available experimental data.
