Amélioration d'un modèle de comportement uniaxial du béton sous charges cycliques alternées
In this study, the model for the concrete behavior is based on the theory of damage, on the mechanics of continuum media and the thermodynamics of irreversible processes. The model takes into account the inelastic strains and the loss of stiffness due to cracking. An important improvement for the application of the model has been made in the method of identification of parameters; it is based on physical data obtained from concrete classical tests and from an analytical expression of a constitutive law of common use. Validation tests have been carried out on standard cylinders subjected to repeated compressive loads and on short reinforced columns under compression-tension alternate cycles. The comparison between the model and tests gives promizing results for analysis of reinforced concrete structures under cyclic loading.
