Thanks Ussuri - In fact, the tank full imposes a load that would overcome the wall weights. I think Jed's on the right track.
Jed, thanks for looking into this for me. I'm trying to get a copy of Batty's tank book, but my deadline for this study phase will overtake bthat effort. Any insight...
Yes, but.. I get it if the moment from water or earth pressure causes moment at the base of the wall. However, the PCA book indicates the base slab is under a separate moment which is additive to the moment in the wall. I can see a foot wide strip of base slab modeled similar to a strap...
Help! I'm analysing an existing circular tank, open top with base fixed to the bottom slab. In "Circular Tanks without Prestressing" by the PCA, it is recommended (section 13) to combine and distribute induced moment from the base slab with moment in the wall in order to accurately predict...
