RE: Location of Primary Wind Girder
stiffening assembly ring located near the top of the shell course of open top floating roof tanks. Maintains roundness when the tank is subjected to wind loads.
secondary wind girder:
increased tank height, resulting in specific portions of unstiffened shell may require adding of a small annular ring at some lower elevation than the primary wind girder
RE: Location of Primary Wind Girder
i want to alter the location of PWG because of change in fire hydrant position.
What may be the range of locating Primary Wind Girder in a tank. The Tank is Cone Roof Tank, not internal floating.

RE: Location of Primary Wind Girder
So should i consider providing only secondary Wind Girder in Cone roof tanks?
And what about Internal Floating Roof Vertical Tanks (IFRVT)?
RE: Location of Primary Wind Girder
Cone roof tanks are not open-top and do not need a top wind girder.
You need to consider intermediate wind girders for all tanks.
By definition, internal floating roof tanks have a fixed roof. If the fixed roof is a cone roof, no top wind girder is needed (see above). If the fixed roof does not add stiffness to the top of the tank ( ie an aluminum dome roof, see G.1.3.1 ) then treat the tank as an open-top tank and evaluate for a top wind girder.
RE: Location of Primary Wind Girder
For fixed roof tank (Cone or Dome) the shell stiffener requirement is determined by the wind speed and tank diameter.

RE: Location of Primary Wind Girder
These are 2 factors that need to be considered as well for shell stiffener.
