Hello. Do you know if hydrostatic pressure applied to a tank's walls can cause the structure to twist?

IIRC from Statics 101, hydrostatic pressure applies normal to the tank walls/containment structure, so I don’t see how any torque can be developed. But, I’m going to follow this thread.

Hi,

Agree with Latexman ,why do you ask this question? 

Any problem with an agitated tank or reactor?

Hi

I'm looking at a project that involves designing a storage tank.

Rings of stiffeners were installed into the tank's top and bottom. Why it is used intrigues me.

There is no information in the API650 ANNEX V regulation that I reviewed. It just specifies the stiffener and section placement height.

Apply the hydrostatic pressure forces during the analysis using a FEA tool. The end effect is a 0.16° displacement twist. I decrease the displacement to 0.5° by applying a stiffener. Use RFEM 5 to perform the analysis.

How may hydrostatic pressure cause the structure to experience torque? Is it possible?

I am not a tank designer,... But in real life it never happen that Hydrostatic pressure gave torc to the tank.
