Wind on Rooftop Equipment, ASCE 7-10 Section 29.5.1

In the above referenced section do the horizontal and vertical forces (Fh & Fv) need to be considered simultaneously or is the intent to examine their effect on the structure separately? I know what is more conservative but I'm unclear on the code's requirement.

(Sorry if this has been addressed before but, if so, I can't remember the response.)

RE: Wind on Rooftop Equipment, ASCE 7-10 Section 29.5.1

i think it's concurrent like an airplane wing

RE: Wind on Rooftop Equipment, ASCE 7-10 Section 29.5.1

How can the vertical wind force physically act separate from the horizontal wind force?

RE: Wind on Rooftop Equipment, ASCE 7-10 Section 29.5.1

Simultaneously. As an aside, you'll find the horizontal and vertical forces are ridiculous because of the GCr values. I don't know who comes up with this crap... must be some college professor who has never designed a building.

Belated thanks. I agree that applying them concurrently makes sense, I was just trying to make sure that that was the code's intent, which, from the sound of it, it is. Thanks again.
