API 650 Low pressure Tank Anchorage

API 650 Low pressure Tank Anchorage

API 650 Low pressure Tank Anchorage

(OP)
I have a tank with an operating pressure of 1" w.c. and a maximum pressure of 4.4" w.c.
The roof connection detail does not meet the requirements of a frangible roof.
Neither the operating pressure nor the maximum pressure exceed the weight of the shell and roof.
However, the maximum design pressure calculated using F.4.1 is 205.5" w.c. This results in an anchor bolt load of 17.65 kips which would require a 10.5'x10.5' x 1' chunck of concrete for each anchor bolt. This does not seem realistic.
Do i have to design the anchorage for the reactions created by F.4.1? Or can I just design it for the emergency venting pressure of 4.4" w.c.?

RE: API 650 Low pressure Tank Anchorage

The design pressure is specified by the owner. The maximum design pressure calculated per F.4 is a limit on what that design pressure can be, but doesn't imply that you must use the maximum value as "the" design pressure.
