Reinforcement for tall tanks with high roof load
Reinforcement for tall tanks with high roof load
(OP)
First time poster, long time lurker.
I would like to amend a closed thread that I was just reading.
thread404-8962: Flat Reinforced Tank Roof
This thread was VERY helpful, but it leaves me with a couple of additional questions.
To recap the problem in the above mentioned thread:
-We have an approx. 12' dia. tank with a 1000# agitator drive to be mounted on top.
-The tank has a flat roof
-How do we stiffen to roof appropriately
I would like to amend this question with a couple of concerns:
-Increase the weight of the agitator to 2000#
-My tank is approx. 45' tall: does this require any concern for lateral forces such as wind, or increase any concern for vibration? Does anyone have any tools (calculations, experience) to comfort me considering the possibility of this tank 'toppleing'?

This tank is anchored. Seismic loads have been considered, although intuition tells me this increased dead load most likely will require re-examination in this capacity.
As for the support system you describe, could you be more specific, i.e. is the grillage of 12" members mounted to the tank shell or is it supported from the ground? Why 12" beams or channel? That seems pretty heavy if welded to the shell, but possibly reasonable if anchored in earth...
