I have defined several load cases and would like to additionally apply a permanently acting prestress as a member load. To which load case is the prestress ideally assigned?

Answer

At this point it is recommended to create load combinations:

First, a new load case "preload" must be applied, see Figure 1. Only within this load case should the corresponding preload be entered as a bar load. The impact category "preload" is considered to be constantly acting just like the dead weight. This includes the load case preload when activating the automatic load combinator in all generated load combinations, see Figure 2.
