Water Tank Wall (Tension Limit)
Water Tank Wall (Tension Limit)
(OP)
Is there any tension stress limit on water tank wall (Liquid Containing concrete wall), the tension from 0-50 cm of bottom of wall is -3 MPa and then from 50 cm to it's full length(5.5 m) the tension is -1 MPa and the fracture stress is -3.5 MPa is this stress (-3 MPa at far end of the wall 0.5 m and then the stress is better)permitted in ACI, we are talking about a water tank wall it must have a tension limit

What I would do is find a copy of the PCA "Design of Circular Concrete Tanks without Prestressing" It's an oldie but a goodie. This will give you an tried and true analytical method and suggest allowables. There's some subtle attributes in circular tanks that you might overlook without it. It sounds like you might either have it or are using an finite element model, which is fine, but I'd check your numbers vs. the PCA document.
Many small bars are better than a few larger bars. Be sure to stagger splices.
