Hello Everybody.
In EC 1991-1-4 for canopie (7.3 chapter) we have coefficients Cpnett and over force coefficients Cf moreover we have 4 pictures with roof and forces.
I do not know when i Should use Cpnett and when Cf.
(As chapter 5.3 says -> Fw=CsCd*q_p(ze)*Cf*Areff)
So here we use Cf but i dont see this force on construction... I have purlins,griders and roof - where i use cpnett, where i use Cf.
In attachment You can find a picture of construction.
Thanks for your help.
