Wind Load on an Open Top Rectangular Tank
Wind Load on an Open Top Rectangular Tank
(OP)
I am designing an open top rectangular SBR and am wondering the best way to consider wind load on the structure. I am designing per ASCE 7-02 and the tank is only going to be out of the ground about 11'. The remaining 14' is buried. I am not so much concerned with the wind pressure as with the wind suction being combined with the internal fluid pressure which is controlling. Normally I would have used Eqn. 6-20 for wind loads on other structures, but then I got to thinking about the potential for suction forces. Am I picking gnat crap out of pepper or would the components and cladding equations be better suited for this situation? How are you guys handling this? Thanks in advance.

Wind loads do have a bigger effect on steel tanks, especially when empty.

I am like Jedclampt, if the tank is full; wind is not going to govern. If it is empty, I still don’t think it will govern because the earth pressure will be your worst load case.
Good luck

Thanks again to both of you for the quick response!
