Elaboration d'un nouveau modèle d'endommagement dans le code de calcul SYMPHONIE-CSTB
The present research work aims at the development of a reliable and predictive model for the virtual evaluation of concrete structures. This work was motivated by the observation of the incapacity of existing models toward the reliable prediction of loads and ultimate displacements under a complex state of stresses, particularly for the mixed modes 1 & 2. This new model is based on certain hypothesis of deformation mechanisms relative to the diverse aspect of the concrete. After its 2D & 3D implementation in the SYMPHONY software, the model was tested and compared with test and other theoretical results, under various scenarios found in the literature, in order to estimate its answer toward a wide combination of requests. The model shows a good capacity to predict the concrete behaviour, particularly for the mixed mode tensile-shear.
