Vertical walls with roof
First, define the standard and, where applicable, the National Annex in the Velocity Pressure dialog section. This specification controls, which text boxes can be accessed.
Specify the parameters as described in Chapter 188.8.131.52.
As described in EN 1991-1-4, Table 7.4a, for example, several load cases must be taken into account for a duopitch roof. In the Load Cases to Generate dialog section, specify the load case numbers for the load generation. The compression loads are created in the load case LC w+, the suction loads in LC w-. The combinations (compression on one side of the roof and suction on other side) are defined as LC w-/+ and LC w+/-. The relevant load cases can be created with the button.
Use the button to scale the loads for specific members. Specifications are entered in a separate dialog box (see Figure 11.187).
After confirming the generator dialog box with [OK], RFEM displays the results of the load generation for all load cases in an overview (see Figure 11.201). The dialog tabs represent an important control option because the external pressure coefficient cpe,10 and the external pressure we are displayed by zones for each load case.
