Reinforced Concrete Tanks 1

[KarlT]

Does anyone know of any specific codes or reference materials for the design and analysis of circular reinforced concrete tanks? (No prestressing or post tensioning...only rebar)

 

[KarlT]

Further to my post, how about for rectangular concrete tanks containing liquids?

Are concrete storage tanks containing liquid required to have a liner, or is it possible to construct them without one? Are there any codes out there that address the specific issue of the requirement for a liner?

Thanks!

ACI 350 is written to provide design and construction guidance for the use of Concrete in Environmental Structures.
As far as specific designs, PCA has a good publication titled "Circular Concrete Tanks Without Prestressing" which gives excellent examples and tables on the design of Circular Tanks. Unfortunately, their publication on rectangular tanks is not so good. The best publication for design of rectangular tanks is the out-of-print "Moments and Reactions for Rectangular Plates" by the United States Bureau of Reclamation.
As far as lining, unless the liquid contains some aggressive chemicals no lining is necessary.

Is there any links available to get the information available in the PCA.
Can you please provide me with that.

I have a Question about multicells concrete tanks.

I found a methodology to calculate the moments in the walls,(PCA Rectangular concrete tanks). But the examples are only with cells that have the same size.

Can I use this procedure in tanks with different cells??

 

[JedClampett]

Most of these methods (I prefer the Bureau of Reclamation Tables) give you fixed end moments. If there is a joint (wall intersection) where there are three different moments, you could do a moment distribution. However, there might be cases where one cell is full and the other empty, doubling or tripling your work. I try to pick the wall with the largest moment (usually the longest) and design all the walls for that moment.
Don't forget shears!
