||In dimensioning reinforced concrete structures in accordance with EC2, an alternativemethod of describing the system load-bearing behaviour is by nonlinear simulations oversignificant periods of the life cycle. The realistic reinforced concrete FE model presented heretakes into account nonlinear material laws for concrete and steel, fracture behaviour andcomposite action as well as viscous behaviour (nonlinear creep and shrinkage). Considering theexample of a reinforced concrete box-type folded plate structure, critical loading situations(especially high shear loads) were investigated which lead to system failure at different times inthe life cycle of the structure. System load-bearing reserves are clearly indicated by resultantstress redistributions.
