[Towertalk] Windload "partway up"

[Mowery Joseph D DLVA]

Mark,
	The shear stress that the tower encounters is the 
same.  However, the bending moment is not the same and 
therefore the reaction at the base of the tower has 
changed.
	If a manufacturer gave me this answer as coming 
from their "Engineering Department," I would have to 
find another manufacturer.

I have been dying to ask Steve this same question, since I think he said in
Dayton that "you just add it all up."  My basic understanding makes me think
that 10 square feet halfway up a 100' tower is not the same as the same load
at the top of the tower.

Herr Towermeister? (don't know how to say that in Klingon.)
