Sažetak:
The paper presents the model and the respective developed software for the static analysis of concrete plates and shells exposed to transient static loads by the finite element method (FEM). A degenerated shell element without membrane and shear "locking" has been employed. The model simulates the influence of material and geometric system nonlinearity. It is possible to include the dominant non-linear effects of reinforced concrete: the development of concrete cracks in tension and yielding of the concrete in compression, the changes in the tensile and shear stiffness of concrete and the nonlinear behaviour of the reinforcement. The influence of the change in the structure geometry is dealt with by using an updated Lagrangian coordinate system. The solved example illustrates the reliability of the model and some possibilities of the application of the model and of the SALJ computer program.
