Lattice tower
« on: January 04, 2009, 03:26:26 PM »
Hello everyone,

I'm looking for informations about lattice towers. I'm looking for advantages and disadvantages of circular tube section and angular section of a lattice tower. Some towers are made of angular section (http://lh4.ggpht.com/_QhrtAOmAaJg/R2HUG0FH0cI/AAAAAAAACi0/XQDA102ky34/100_8528.JPG and some with tube http://img.alibaba.com/photo/11702156/Gsm_Tube_Tower.jpg.
Tube is good for windload, snow, esthetic. A little bit expensive because it's welded. But why do we use angular section.

I'm looking for any informations which could help me (links, books, thesis,...).

Also I'm looking for informations about circular flange connection of tubular section in lattice towers (like in the second link). How do you calculated the strain, the stresses.. in the flange in the bolds. You can calculat it with finite element butr I want to know if there is simplified formula which give goods results.

Thank you for anu help
