The towers represent
about 15 to 20% of the total installation costs and optimized design may therefore
lead to substantial savings with regard to costs and use of materials. Some of
the most interesting design and manufacturing details are connections used to
assemble sections of tubular steel towers supporting wind turbines. There is
traditional flange ring connection and on the other side, as a new proposal,
friction connection. In this paper theoretic basis of design of friction
connection of wind towers is given.
