Load Combination Regulations EC7

[stroxy]

In ULS verification under EC7, partial factors for variable actions may be taken as 1.5 if unfavorable and 0 if unfavorable.  Does the regulation file consider this? I notice only the value of γ-max (=1.5) is defined whilst the field for γ-min is blank.  Please see attached

When the code combinations are generated they include ones that include only deal loads (live and snow loads with 0 load factors) dead loads and live loads (snow loads with 0 factors) and dead loads with selected live loads (other live loads with 0 load factors) therefore there is no need to put 0s as the load factors in the regulation file.

Thanks Artur, what about the scenario where different limit states recommend different values for γg, as in the attached tables.  How does one incorporate this in the regulations?

[Artur.Kosakowski]

The A type with 0.9 for dead loads is used in the PN regulation whereas additional reduction of dead loads due to existence of live loads is used in the Belgium version of Eurocode.

So if I understand you correctly, that means to check the 2 limit states EQU and STR for example, I will have to run 2 different analysis with the corresponding regulations for each limit state

One analysis with two sets of combinations generated with different regulation files. The steps are shown on the attached picture.
