How to find natural frequency of pole?
(OP)
Hi
I need to find the natural frequency of a tall, hollow steel round pole. basically it is a hollow steel pipe, 16" diameter.
Does someone know the equation for this?
Thanks

I am glad to see an equation. I used Staad to output the frequency, but not having enough experience with this, I wanted some manual equations to compare with. It is not in seismic zone, and is to find the gust factor for wind loading, to determine if it is considered a flexible structure, with the higher gust factor.
It might be overkill for a foul pole, but the stadium is municipally owned, and they are a good customer of ours, so I don't mind the extra effort.
Thanks for the Rourk's tip, I have a copy (as all engineers should) but didn't think to look in there.
