RE: Elevated Water Tank Evaluation

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

Use AWWA D100 ( American Water Works Association)
Also a good reference is Steel Plate Engineering Data by Steel Plate

AWWA D100 has wind loading criteria.  Some engineers prefer ASCE 7 for
detailed wind analysis on new designs.  I expect that ASCE 7 will be a
problem for an old tank.

Subject: Elevated Water Tank Evaluation

Our firm is being asked to evaluate an existing elevated water tank for
corrosion and structural adequacy.

I know there have been some threads on tank design, but it seems most are
related to fuel tanks.

Anyone know what national standards are used for the design/evaluation of
elevated water tanks?  Design considerations include typhoon (hurricane)
wind loading as well as seismic.

Any help would be much appreciated.
