Thanks to all. All comments help me in certain way.
The analysis with Octagon shape was done last weekend . I came up with the Net Allowable Bearing of 3 ksf. The Geotechnical Report is not submitted to us yet, but it is likely that the Net Allowable Soil Bearing capacity will be 3 ksf which...

StructuralEIT,
Thanks. I understand your first paragraph, but not the second paragraph.
I am very interested in :
1) knowing "do the geometry and algebra exercise"
2) knowing how to "end up with a quadratic equation that will tell you the distance of the pressure diagram and the maximum...
csd72,
Thanks for the comment. I would, but octagon is preferable and very popular in PetroChem Industry.
StructuralEIT,
Thanks for your reply
Yes, if full bearing, then P/A ± M/S is enough.
But I need to analyze it in some load cases such as empty vessel plus full wind of 130 mph that may...
I have an 1' thick existing OCTAGON FOOTING down below the grade. On top of the octagon footing is an smaller existing octagon pedestal. The pedestal is 6' thick and 1' above the grade.
The existing foundation is currently supporting an old vessel. The old vessel will be replaced with a new...

This is an existing foundation that will be reused to support a new vessel if possible. The old vessel is replaced with a new vessel of the same kind.
My task is to check if the existing foundation is adequate to support the new vessel.
The base shear and the moment (due to wind load...
DarthSoilsGuy,
It is a good idea. However, octagon foundations have being used for long time that I guess there are particular approach and formulas to calculate the base pressure for this type of shape.
If I do not have anything when the time comes, I will treat it like a round shape as you...
I have an 1' thick OCTAGON FOOTING down below the grade. On top of the octagon footing is an smaller octagon pedestal. The pedestal is 6' thick and 1' above the grade. There are vertical load, moment, and shear on top of the pedestal. I can calculate the total moment M and vertical load P at...
