Matériaux et Construction Aims and scope Submit manuscript

Summary

Secondary stresses arising from the interaction of the heterogeneous components of concrete are shown to influence the elastic and time-dependent strains in all directions, even under a uniaxial compression. The influence of creep of aggregate and the stress at the aggregate-matrix interface under sustained load are also considered. It is suggested that superposition of strains under multiaxial stress is not valid.

Résumé

On montre que les contraintes secondaires engendrées par l'interaction des composants hétérogènes du béton agissent sur les déformations élastiques et sur la déformation en fonction du temps et dans toutes les directions, même en compression uniaxiale. On examine aussi l'effet du fluage des agrégats et les contraintes à l'interface agrégat-mortier sous charge permamente. On suggère que la superposition des déformations sous effort multiaxial n'est pas valiable.
