For a 3 sided structure with an open face, would you apply both windward and leeward wind pressures to wall opposite of the open face?

See the image below for what this structure would look like. I believe this would be partially enclosed per ASCE.

Enclosure classification is by direction, right? Windward openings over balance of openings. Dead-on, I’d call that partially open or perhaps partially enclosed. Not sure I’ve ever thought about a three-sided building before.

I guess this building doesn’t have an interior in the short direction? Now I’m itching to check ASCE 7-22. Someone else will likely beat me to it.

I’m not familiar with ASCE but the net pressure coefficient on the wall should be in the order of 1.2 to 1.3.

Ok final answer: partially enclosed, apply (+) internal pressure and (-) external pressure simultaneously to leeward wall. Sorry for the panicked responses!

That's what I was thinking too. If you look at the wind flow path, I would think it would push on that windward side of that wall and definitely create a negative pressure that pulls on it of the leeward side.

And, it' is surprising how little protection partially enclosed structures get from being partially enclosed.
