Ultimate Limit State
This column lists all load cases, load combinations, and result combinations that have been defined in RFEM.
Click to transfer selected entries into the Selected for Design list on the right. You can also double-click the items to transfer them. To transfer the complete list to the right, click .
Selecting several load cases is possible by clicking them one by one while pressing the [Ctrl] key, as is common in Windows applications. This allows you to transfer several load cases at once.
If a load case is marked in red, like LC3 in Figure 3.6, it cannot be calculated: It indicates a load case without load data or a load case containing imperfections. When you transfer it, a corresponding warning appears.
Below the list, several filter options are available. They help you to assign the entries sorted by load cases, load combinations, or action categories. The buttons have the following functions:
Selects all load cases in the list.
Inverts the selection of load cases.
The column on the right lists the load cases, load combinations, and result combinations selected for the design. To remove selected items from the list, click or double-click the entries. To empty the entire list, click .
You can assign the load cases, load combinations, and result combinations to the following design situations:
- Persistent and Transient
You can change the design situation by using the list that you can access by clicking at the end of the input field.
Just like before, a multiple selection is possible by keeping the [Ctrl] key pressed, thus allowing you to change several items at once.
The analysis of an enveloping max/min result combination is faster than the analysis of all load cases and load combinations indiscriminately selected for the design. However, when analyzing a result combination, it is difficult to discern the influence the included actions have (see also chapter 4.1).
