[eriksasha]

I'm trying to set up an excel spreadsheet for BS8100 concerning wind loading on masts but have not been able to find an equation for determioning Kr (terrain roughness factor).

Does anyone out their know the equation?

You are in the wrong area - either post it in the appropriate engineering codes area, or in the structural engineering other topics.

You will get more responses that way.
