5.6.2 Generated Combinations

Generated Combinations

When switching to the Result Combinations dialog tab or to Table 2.6, RFEM automatically creates the combinations. As the load cases are not superimposed manually, the General tab looks different (see Figure 5.40 for user-defined combinations).

Result Combination No.

The result combinations generated from action combinations are numbered consecutively.

In the bottom left of the Existing Result Combinations dialog section in the Loading dialog box, you can filter the generated combinations according to different criteria.

Result Combination Description

RFEM assigns brief descriptions, which are based on the combination rules (safety factors and load case numbers). You can change these descriptions, if necessary.

Click the dialog button to jump back to the Action Combinations dialog tab (see Chapter 5.4) where the action combination that the current result combination was created with is selected.

To Solve

The check box controls the result determination for the result combination(s) selected in the Existing Result Combinations dialog section.

Loading in Result Combination

The columns provide information about the load cases, including the corresponding partial safety factors and combination coefficients. It is not possible to modify the factors of generated combinations.

If a load case is assumed to be Leading in the combination, it is marked accordingly in the dialog box.

To check and, if necessary, adjust the partial safety factors and combination coefficients, use the [Details] dialog button. The Coefficients dialog box is divided into several tabs (see Figure 12.27 and Figure 5.24).

Adding result combinations

The generated result combinations cannot be edited, only deleted or excluded from the calculation by using the To Solve check box.

With the [New] button in the bottom left of the Existing Result Combinations dialog section, you can add a user-defined combination. The look of the General dialog tab is adjusted to enable the manual definition.
