If necessary, you can create load combinations manually. In this case, Tekla Structural Designer uses a default factor for each loadcase when you add it to the combination.

1. On the Load tab, click Combination.

   The Loading dialog box opens on the Combinations page. On this page, you can see all currently existing load combinations.

2. Click Add.
3. In Design Combination Title, name the combination.
4. In Class, select the combination class.
5. Depending on the combination class that you selected, do some of the following:
   • Select Active in order to include the combination in analysis or design.
   • Select Strength in order to assess the combination for design.
   • Select Service in order to assess the combination for deflection.
6. In the left side pane of the Loading dialog box, click the combination name.
7. Select the loadcases that you want to add in the combination, and click >>.
   Note:

   If Min Lateral Load cases (of type MLL) exist, you cannot add these to your combination until one of the existing gravity combinations has nominated for calculating the values. To do this, select the required combination and check 'Minimum Lateral Loads' on the Parameters tab as shown below.

   

8. Click OK to save the load combination.

   Tekla Structural Designer adds the new load combination to the list of combinations in the Loading list.

   Tip: To review the factors and options that have been applied to a combination, click the combination name on the left side pane of the Loading dialog box.
