Torsionstragverhalten eines Segmentturms mit alternativer Fugenausbildung.

Torsional behavior of a segment tower with an alternative joint design Based on the most commonly constructed segment wind turbine towers at present, a further developed design of joints is described in this article. The dry joint which works without balancing layer of epoxy or cement mortar has been applied to wind turbine towers in the horizontal direction for many years. It should also be applied in the vertical direction. The evenness in the joint will be assured with the help of a high‐precision milling machine. Therefore, the compactness and force transmission of the construction can be guaranteed. However, a decrease of structural resistance is still observed through numerical simulation. By changing the integral cross section to an open half‐ring segment, the weak part can be easily pointed out in the structure design itself and also by current design approaches. There are currently no suitable theories or regulations for this kind of structural design. [ABSTRACT FROM AUTHOR]
