National Annex

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

Click the [Edit] button 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 that is available in every input window.

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, compression strut angles, etc., you can adjust the parameters. To do this, first click the [New] button to create a copy of the current National Annex. In this user-defined Annex, you can then change the parameters.
