Wind upon curved structure

[ITV]

Dear sir/madam,
i have to analyse the attached curved structure. 5x5m approximate dimensions per span.
Which parts of the Eurocode would you refer into to calculate the wind load and the snow load?
I would choose:
"Figure 7.12, par.7.2.8 Vaulted roofs and domes-domes with circular base" of Eurocode to calculate wind.
and
"Fig. 5.6 Snow load shape coefficients for cylindrical roof - Cylindrical roof" of Eurocode to calculate the snow concentration.

What do you think?

If I understand you figure correct I would consider it a canopy roof. You basically seem to have a parachute and I think the windloads may be considerable.

- One of the approaches is vaulted roof ..However , in your case the structure is open canopy and internal pressure shall be considered. My suggestion would be considering one or duo pitch canopy and vaulted roof and take the more stringent one. Pls have a look NA to BS EN 1991-1-4:2005

- Yes..OK..
