Wind Load/ Shape Factor For Circular Steel Tanks
Wind Load/ Shape Factor For Circular Steel Tanks
(OP)
Hello,
Working to British Standard BS6399 does anyone know a good shape factor to use for a circular steel tank 13.8m diameter?
I've calculated my dynamic pressure qs to be 1.13kPa. Once I have applied a shape factor, over what area do i apply this?
Please Help!
thanks
John

In the current API-650, that load is applied, but also uplift on the roof is used as well. But also, load combinations have been revised, and some allowance made for the fact that tanks are seldom completely empty.
It helps if the wind loading and the overturning criteria are all taken from the same standards.

The correct term is Imperial units.

It's not a simple shape factor, but rather a pressure coefficient which varies around the perimeter.

Thanks for your help peeps! Great forum, its the first time i've used it. i'm sure i'll be back.
