Whereas plates are characterized by membrane actions and slabs by bending actions shells combine both. As a further extension shells may be curved in space. A proven finite shell element is described in the chapter allowing for these features within a continuum based approach. This permits an explicit modeling of reinforcement layers combined with a variety of nonlinear multiaxial material laws for concrete. Its application is demonstrated with reinforced concrete slabs exposing self‐equilibrating membrane forces besides bending moments due to concrete cracking. This also highlights current potentials and limitations of numerical simulation for reinforced concrete structures. Furthermore, another example for model uncertainty is described with using alternate models for concrete.
