ABSTRACT
A layered shell formulation allowing us to apply three-dimensional material laws within the different layers is described. The formulation is combined with a rate-independent plasticity constitutive model for plain and reinforced concrete. A fracture energy regularization in the softening branch is used in the constitutive law of concrete. The reinforcement is described as a smeared layer within the shell-discretization representing also the effects from tension stiffening if necessary. Several examples demonstrate the applicability of the proposed model.
