Help with combinations using CM66 (France)

[anacffaria]

Hi,

I'm doing a model with norms NV65 and CM66.
When I do automatic combinations, a value for "Extreme Snow Coefficient" shows up, and I don't understand what it's for, how it might impact the results and the meaning behing it. Can someone please explain it to me?

See the attached image to clarify.

Thank you in advance,

Ana

Hi @anacffaria 

Combination is :  G + 1xVent ext + 0.5xNeige ext + SigmaQi

If you haven't created a Neige extr load case robot will use 0.5x1.667xNeige

If you have created a Neige extreme from table below, Robot will use 0.5xNeige extreme
