Wind Pressure on Roof
Wind Pressure on Roof
(OP)
Hi everyone,
I am an architectural student that has just started learning about wind engineering. I have a bit of a problem trying to understand how the wind pressure works in a building. In what situation will the roof pressure act alone on a building?

RE: Wind Pressure on Roof
So this is a complicated question and you need to have the proper references to answer it. I don't think this is what you wanted to hear, but that's why we make the big money.
RE: Wind Pressure on Roof
Thank you for your reply.I was actually wondering about a situation like the image below.
I'm not too sure in what condition will cause the pressures to act in such a way.
RE: Wind Pressure on Roof
- The aerodynamic effect of the wind traveling over the building, like a wing,
- The inherent leakage of doors, windows and other openings (intentional and not) into the building. Wind gets in, but it can't get out. Depending on the size and position of the intentionally open ones, the pressures can be relatively small (less than 20%) or be over one half of the wind pressures.
If you're asking why some upward wind acts at the bottom chord of the truss, it might have a ceiling covering it.RE: Wind Pressure on Roof
RE: Wind Pressure on Roof
Thank you for your explanation. I could kind of understand it now.
RE: Wind Pressure on Roof
Thank you for your reply and explanation. I could understand it better now.
If that's so, does that mean that if the pressure acts like the image below:
There is an opening in both the leeward and windward wall only? And for the image below, there are openings on the windward and side walls only?
