Google Translator: I would like to calculate a hall frame with loads from a crane runway. I am not quite clear what the different impact categories mean. Can you explain this to me?

Answer

In the standard EN 1991-3 the load groups 1-10 are given in Table 2.2. These are to be equated with the designation of the classes in our software.
The inclusion in categories AE is a Dlubal own name.

Category A: Limit state of carrying capacity> Table 2.2 of the standard: ULS (1-7)
Category B: Test load (8)
Category C: Extraordinary (9,10)
Category D: Limit state of serviceability (11-13)
Category E: This was included in the combinatorics on customer request and should be used for the load cases in which bearing forces from the crane runway calculation are to be combined with the further construction.

In our Knowledge Base article it is pointed out that the combinatorics (classes AD) is to be used for the preliminary design of crane runway girders For the supporting construction (consoles, supports, bars) this combinatorics is not to be used.
In your case, the bearing loads from the crane runway calculation would only be considered in category E.
