Abstract

Many plate structures in buildings and bridges cannot be handled as isotropic plates. Stiffeners may occur, and can be different in two orthogonal directions. The multi-cell plate in Figure 20.1 is an example. The figure shows that FE models are possible on different detailed levels. Model 1, consisting of a spatial assemblage of isotropic volume elements, explains the behaviour best. However, the input is complicated and the output massive and complex. The calculation results appear as stresses at nodes and are not easy to interpret or to translate into dimensioning of pre-stressing and reinforcement.
