Reinforcement in a concrete structure is often determined based on linear elastic stresses. This paper considers computation of the required reinforcement when these stresses have been determined by the finite element method with volume elements. Included are both tension reinforcement and compression reinforcement, multiple load combinations and crack control in the serviceability limit state. Results are presented of seventeen stress state examples.
