Modelling of Concrete Shells Exposed to Long-term Static Loading

The paper presents the model for the analysis of concrete plates and shells exposed to long-term static loading. The model simulates the influence of material and geometric system nonlinearity. It is possible to include the dominant nonlinear effects of reinforced concrete: the creep, shrinkage and aging of concrete, the development of concrete cracks in tension and yielding of the concrete in compression, the changes in the tensile and shear stiffness of cracking concrete and the non-linear behaviour of the reinforcement. A degenerated shell element without membrane and shear “ locking” has been employed
