Abstract
A wide experimental study on dynamic behaviour of concrete has been carried out by means of the Hopkinson Bar Bundle. In order to study the effect of the internal relative humidity on the tensile behaviour of concrete loaded at different strain-rates, some specimens have been subjected to three different curing conditions and then tested under quasi-static, soft and hard impact loads. A physical approach is also proposed to explain the observed variation in strength.
Résumé
Une large campagne d'essais dynamiques a été réalisée en traction à l'aide du système de multibarres de Hopkinson. L'étude est axée en particulier sur l'effet de l'humidité relative interne par rapport au comportement dynamique en traction à différentes vitesses de déformation. Les échantillons ont été soumis à trois différentes conditions de maturation. Une approche physique est aussi proposée afin d'expliquer la variation de la résistance du béton.
