Design/Analysis of Steel Rectangular STP Tank
Design/Analysis of Steel Rectangular STP Tank
(OP)
I'm an Enviro Eng who knows about about sizing the tanks already but needs to tackle the analysis and structural design of steel tanks for a project. I am accustomed to designing reinf conc. tanks but have had very little experience with steel. And it's been a while since college. Does anyone know any good quick concise books or resources to study up on this? When you google all you get is water tanks on towers and undergroung fuel tanks.

2. Steel tanks are perfect for tension ("hoop stress"), but very sensitive to non-uniform lateral pressure, which is typical during the backfill process. Think of a soda can. Holds lots of pressure but you can crush with your hand.
3. Steel tanks are mostly design-build. Better to spec a tank than build one.
I am a steel guy, and I'm sure below grade steel tanks are still done in some corners of the world, but not a good application.

For the actual design, there are flat-plate formulas in Roark's Formulas for Stress and Strain, among other sources.
Because tanks like this are seldom built, there's not any design standard for them or any set way of doing things.
In the actual design, you'll need to optimize material costs versus labor costs (you can use thicker plate and fewer stiffeners, or thinner plate and more stiffeners, for example) and this is one reason it's advantageous for the actual fabricator to do the detailed design.

Try to talk whoever has this wacky idea into a round steel tank above grade or a concrete tank below grade.

I think it is better to have the tank made of reinforced concrete for durability purposes.
good luck
