Wind pressure estimation

[bethcuff]

Looking for advice on applying this formula:



To a shape like this:



As the only drag coefficients I can find are for simple shapes? Any advice appreciated thank you!

Is this vertical, horizontal, and what is the shape?

https://www1.grc.nasa.gov/beginners...arison shows that,the amount of drag produced.

Hi, it would be horizontal wind load on the shape shown in the bottom screenshot, looking for the worst case scenario. I need to consider the wind from all directions but horizontal only for now.

Just do it for a square shake 55 ins square, or 60 ins square to be a bit conservative.

Our stick it in a wind tunnel

Use the diagonal of the section.

Wind pressure formula per. IBC 200

Wind Pressure Exerted on Vertical Wall

Wind Pressure and Force Exerted on Vertical Wall Equations, The wind can vary both in terms of its speed and its direction. As a result different pieces of equipment are needed to measure these different characteristics. Wind direction is commonly determined by weather vanes or wind socks which...

The following excerpt from Eurocode 1: EN 1991-1-4,
Although the force coefficient is an empirical factor that should be typically determined through experiment for the shape , an approximation could be predicted assuming suare section with rounded corners ,

My vote would be Cf=2.1*0.7 = 1.5
