How can I consider the partial safety factor γQ,T in the automatic load combinatorics with 1.0 in compliance with DIN EN 1992‑1‑1/NA: Chapter NCI (3) or DIN EN 1990/NA Chapter NDP A.1.3.1 (4)? The value γQ,T = 1.5 is used by default.


To apply this in the program, it is necessary to copy the "Temperature" load case (see Figure 01). All loads contained in the load case will be copied as well. One of the load cases is used for the ultimate limit state (ULS) load combinations, the other one for the serviceability limit state (SLS). The loading in the load case for ULS is now multiplied by 1.0/1.5 = 0.667 (see Figure 02).

In order to ensure that both load cases do not occur simultaneously, but only for the specific design situation, the exceptions are determined in the respective combination expressions. For ULS, it is quite simple to define the dead load case in the way that it is not combined with the temperature load case for SLS (see Figure 03). SLS applies exactly the other way around, that is, the load case of dead load is not combined with the temperature for ULS (see Figure 04). In this case, the "Differently for each combination expression" option must be activated.

The desired load combinatorics is then obtained (see Figure 05).
