Reference height for cladding wind loads

[gmanos]

Dear all,

For the calculation of the wind load on a cladding element, which height should we consider, the building height or the specific cladding panel height?
I am mainly interested for the eurocode EN 1991.1.4.
Thank you in advance.

in ASCE you'd usually see the negative pressure govern, negative pressure is based on the full height of the building (qh?), as I recall. Can't speak to Eurocode. Sorry. It's possible positive pressure would govern, but it increases with height (qz) and the coefficients on windward/leeward make me thing the leeward (negative pressure) will typically govern.

Regards,
Brian

Thank you, in eurocode negative loads are the most critical as well, at the edges of buildings in plan view.
