I'm trying the new TANK "wind profile" function, that defines the wind pressure at different heights.
I am used to use this feature in PvElite too, and pvelite clearly states that the user should input pressure values already factored with the correct shape factor (0.7 or 0.8 or whatever the designer prefers).
Note from PvElite: Wind pressures defined in the above fields should include the appropriate wind shape multiplier for the vessel which is generally less than 1 and grater than 0.5
This means that pvelite will NOT correct the wind profile and it will use it "as is".
Now, going back to TANK, there is no similar hint in the "wind profile" window.
I assumed that, TANK would require factored pressure too, just like PvElite, but in fact the program is not stating this, and the user manual too..
The point is that I have a spreadsheet which gives me the overturning from a given geometry and a given wind pressure, and if I cross-check with TANK results, the resulting overturning calculated by TANK is way lower (40% - 50%) than the one calculated with the spreadsheet.
I have the doubt that TANK is not requiring a factored wind profile, but is requiring a "pure" wind pressure without any shape coefficient. Then, during analysis, the wind profile will be factored again.
Is this what the software is doing?Otherwise, I can't find an explanation to understand why Tank is giving me a wind overturning which is lower than the spreadsheet overturning (the obvious explanation would be that the spreadsheet is wrong :P ... I am checking this too, but it has been used for a while now, without major objection by customers and fabricators...)
