Steel Water Tank Foundation

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I was asked to research a foundation design for a large steel water tank.  The tank is about 50 feet diameter and 24 feet tall.  It looks like a typical oil field tank.  Are there publications that give foundation design recommendations for large diameter tanks?  What is the best source of design criteria?


The owner has stated that typically they put down sand and gravel and sit the tank directly on that.  Then they build a steel ring around the tank, beyond the tank perimeter,  to contain the soil underneath.  Is this a common procedure?  I would have expected a concrete ring footing below the tank.


If a concrete ring footing is used, does it only carry gravity load, or is it subject to tension forces from horizontal forces from the soil as well?


Thanks for any insight you can give.
