A little bit of mathematics may be understatement. K7NV did a nice piece
of computer analysis on guyed towers (see http://k7nv.com/notebook/ ) which
at least illustrates the thought process and some of the non-intuitive
things that can happen. It strikes me that there's a reason why self-supporting tower designs all taper from the bottom -- presumably a lot of the steel in an unguyed straight tower is overkill near the top and insufficient at the bottom. I also haven't seen any discussion in this thread about the size of the concrete base that would be required, or the way the tower would be anchored to the concrete. 73, Pete N4ZR At 12:54 AM 1/14/2005, Jan Erik Holm wrote: Dont you guys ever do calculations on things like this? A little bit of mathematics will figure all this out, also I´m pritty sure there would be computer software that can do stress calculations on towers depending on how much load you put on them etc etc. Used to do this when I was in the university, however it was 30 years ago and darn it if I can remember how to any more, should be able to study up on it I guess. However these days I guess you do it in computers and not by hand and brain. _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
