Abstract

Part 3 of the present series gives the prediction formulae for the average compliance function in the cross-section of a specimen exposed to drying at constant temperature. The formulae describe the additional creep due to drying by means of the shrinkage function, which automatically introduces the consequences of diffusion theory, such as the dependence of creep on cross-section thickness and shape. The prediction formulae are compared with 19 different data sets from the literature, which reveal relatively good agreement, better than that with previous models. The main source of error is insufficient knowledge of the effect of mix composition and concrete strength. It is advisable to avoid this error by carrying out short-time measurements whenever possible.

Resume

Dans le troisième volet de cette série, on présente les formules de prédiction pour la fonction de compliance moyenne dans la section transversale d’une éprouvette soumise au séchage à température constante. Les formules décrivent le fluage additionnel causé par le séchage au moyen de la fonction de retrait qui introduit automatiquement les aboutissements de la théorie de diffusion, tels ceux qui font dépendre le fluage de l’épaisseur et de la forme de la section transversale. On compare les formules de prédiction à 19 séries de données prises dans la littérature, qui présentent une assez bonne concordance, supérieure à celle obtenue avec les modèles précédents. La source principale d’erreur réside dans une connaissance insuffisante du dosage et de la résistance du béton. On conseille d’éviter cette erreur en effectuant des mesures à court terme chaque fois que c’est possible.
