Abstract

Model uncertainty associated with the maximum strength, ductility and toughness of high strength concrete confined by rectilinear ties is statistically quantified for ten analytical models. These models are applied to predict the results of 108 large-scale specimens tested under uniaxial compression. An empirical model is proposed for the complete description of the stress-strain curve of tie-confined high strength concrete and proves to be in good agreement with the aforementioned data.

Résumé

L’incertitude du modèle vis-à-vis de la résistance, de la ductilité et de la dureté du béton à haute résistance confiné par armature transversale rectangulaire est évaluée pour dix modèles de calcul. Ces modèles sont utilisés pour évaluer les résultats de 108 spécimens à grande échelle soumis aux sollicitations de compression uniaxiale. Un modèle empirique est ensuite proposé pour la description complète de la courbe contrainte—déformation du béton à haute résistance confiné par armature transversale, et elle se trouve en bon accord avec les résultats expérimentaux cités cidessus.
