There was a NJ engineering firm study done 25-30 years ago on tower failures.   
It was mostly about commercial towers more than 200' high.  They all fell 
within 30% of their height.   I think they were mostly guyed towers.  You may 
find that K1VR referenced it in his book on antenna zoning issues.   I assume 
there must be something done more recently.
