Gunnar Olsen Study: This study is of guyed tower failures and collapses to investigate what a typical tower fall radius would be. He determined that all of the debris would impact the ground within a circle with a radius which would not exceed 29% of the tower height. This is a draft of the study from 1985 by Gunnar Olsen, Jr., P.E. and is many generations of copies from the original so I apologize for the poor quality.
