This is the first time I have had to detail something like this and I want to make sure I have taken everything into consideration. I have a 48 inch diameter pipe to be cast into the wall of a concrete tank with a 25 foot high wall. There is also an existing tank where this 48" diameter pipe...
I have modelled a 10 ft by 10 ft concrete plate with a hydrostatic load to verify the output against plate formulas in "Roark's Formulas for Stess and Strain" So I can apply to a concrete tank model. Using the quadmesh tool, I need about a 3" mesh before results seem to converge.
Is this...
Can anyone recommed a book or design guide to calculate by hand the horizontal moment and shear induced at the corners or a rectangular concrete tank with walls designed as vertical cantilevers?
I have "Reinforced Concrete Reservoirs and Tanks" by G.P Manning with a graph of the shear and...
I am working on a rectangular SBR tank for a wastewater treatment plant, and I reviewed some standard details on drawings we have by another engineering firm. For liquid containing tanks they add extra steel, same size and spacing, at the corners offset with the main reinforcing.

I don't know if anyone happened to read any of the letters to the editor in the October Edition (pg#8). In short the article was about "dummy" members that the author felt were displayed incorrectly on an elevation drawing.
My question is about a comment the author made regarding "dummy"...
I am using Roark's 6th Ed for a flat plate with straight boudaries. I tried one case in Table 26 Case 8.b which is fixed on all four edges and has a uniform load over a concentric circle.
My question is why are the max bending stresses are not shown? The article for this table says that max...
