Wind load on Open structure v.s. Sign
Wind load on Open structure v.s. Sign
(OP)
Is it conservative for a quick calculation, that wind load on a steel truss (an open structure)be treated as solid plate (like long rectangle plate/sign)?
My boss tells me rather than calculating wind load on an open structures (on a face of truss) assume it is like a free standing wall or a sign, this sounds alright unless there is something we are missing?
I appreciate your comments.
Thank you

Can you explain this? I'm not following.

I am not following too. I am kind of freshman. Can you please explain it more in detail?
Thank you very much.

Thank u for both of you but the statement of "If there are multiple frames/members stacked behind each other, the projected area is the same, but the wind loading is increased, and it may not be conservative to treat that as a solid surface." doesn't click for me can you possibly explain it more in detail how it won't be conservative for trusses behind the first one?
Why I should I worry for trusses behind? I use the first truss load and apply it to them
Thank you

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

I also don't think the newer MBMA Building Systems Manual use the same exact method but again I don't have the manual in front of me. The method may not apply to trussed towers.
Hope this Helps.
