National Annex

For the design according to Eurocode (EN 1992-1-1:2004/A1:2014), you have to specify the National Annex whose parameters apply for the checks.

Figure 3.3 National Annexes for EN 1992-1-1

Click [Edit] to view the preset parameters (see Figure 3.4). You can also access the Parameters of National Annex dialog box with the [Nat. Annex] button available in every input window.

Figure 3.4 Parameters of National Annex dialog box

In this dialog box, you can find all design-relevant coefficients specified in the National Annexes. They are listed by the Eurocode's clause numbers.

If other specifications apply for partial safety factors, reduction factors, concrete compression strut angles, etc., you can adjust the parameters. First, click the [New] button to create a copy of the current National Annex. In this user-defined Annex, you can change the parameters.
