In this contribution the authors present new concept for the numerical simulation of reinforced concrete structures based on the coupling of damage and elastoplasticity. Different inelastic processes are taken into account within three‐dimensional rebar‐elements. Concrete is treated as a composite which is described by the damage evolution of mortar and elastoplastic response of aggregate. Furthermore, the application of the microplane theory to the damage description at the interface between concrete and reinforcement is discussed. Special attention is given to the formulation of efficient numerical algorithms. The results of finite element analysis using the proposed concept are presented for some typical reinforced concrete structures.
