Reinforced concrete structures are built all over the world. The development of cracks is an unavoidable appearance, based on the interaction of the concrete and the reinforcement. The crack pattern can have an significant influence at the ageing of the structure. The presented modelling concept describes the reinforced concrete on the mesoscale. For the description of the concrete the Discrete Element Method (DEM) is used. The plain concrete is discretised by spherical particles. Spherical particles, surrounded by an rigid hull, are also used to describe the reinforcement. For an interaction between concrete and reinforcement massless virtual particles are added inside the reinforcement. With this concept a resilient bond behaviour without sliding can be described.
