Elevated Tanks
Elevated Tanks
(OP)
Hi, what are the main parameters that structural engineers require in designing foundations for elevated tanks? Also, assuming that it can be a pillar or multi-column tank. I expect that overturning and therefore uplift resistance may one of the controlling foundation requirements. The tank is most likely to be supported on shallow foundations with gravel soils as the bearing layer at GL -2 to 3 meters.

Buggar, to address sensitive soils against cyclic loadings, we do not allow the 1/3 increase of allowable bearing pressure for short-term loading.
Thanks again !!

In that case, note that the AWWA specifications have some requirements for overturn criteria, seismic loading, wind loading, etc., that are different from ASCE 7.
