The foundation in load case 2 is only effective for the right part of the surface. The foundation in load case 1 is effective for the entire surface. The elastic foundation of the slab is ineffective in case of tension. The self-weight is not taken into account. In load case 1, the surface load acts on the entire plate in load case 2, it stresses only part of the surface. Two load cases act on a slab with elastic foundations: The following example is used to demonstrate the subject. The same applies to models with nonlinear elements. If you want to calculate combined load cases according to the second-order or large deformation analysis, you generally have to create load combinations.
These Settings also affect the appearance of the Result Combinations dialog tab in the Edit Load Cases and Combinations dialog box. Load cases can be combined manually (see Chapter 5.5.1) or superimposed automatically by RFEM (see Chapter 5.5.2), depending on settings in the Model - General Data dialog box (see Figure 12.23).
