[TowerTalk] Rebar

[K7LXC@aol.com]

Howdy, TowerTalkians --

      Working with my PE on a Trylon Titan self-supporting tower drawing/calc 
package, I found out something interesting. Since the vast majority of the 
tower base concrete is below grade, the purpose of the rebar isn't 
structural. That is, it doesn't have to help hold any exposed concrete 
together. It turns out that the primary purpose for rebar in the tower base 
is to control concrete shrinkage. That was news to me.
