Type of roof for Storage Tanks

RE: Type of roof for Storage Tanks
Using the diameter criteria eg: For tanks up to 10m a self supported cone could be used, 20-30m a supported cone roof and a 40m plus dia a dome roof (probably a geodesic dome) may be considered.
At the end of the day its an engineering judgment call or based on client requirements.
Hope this helps
RE: Type of roof for Storage Tanks
Generally, a light product (gasoline, for example) is going to require either an internal or external floating roof or some type of inerting/ vapor recovery system. The exception being smaller tanks.
Generally, a heavy product (diesel, fuel oil) can be stored in a fixed-roof tank wtih no floater.
For a small tank, a self-supportign roof is easiest, for a large tank, a structuraly supported cone roof.

But....
What I have always wondered is:
- When is an umbrella roof selected over a cone roof ?
and
most importantly,
Under what non-subjective criteria is a domed roof the best choice ?
No, feelings, sentiments or recollections please....
Give me a hard reference for domed roofs....

In most cases where an umbrella is used, a self-supporting cone could also be used. The choice between the two involves owner preference and cosmetics more than anything. At the upper limits of size, a self-supporting cone will be very steep.
