Abstract: A method of assembling a wind turbine tower by stacking a plurality of annular sections made of concrete above each other. The main connections are performed between two adjacent annular sections, for withstanding loads induced by a rotor. The auxiliary connections are performed between two adjacent annular sections, for withstanding loads induced by an earthquake and loads induced by the wind on the wind turbine in absence of the rotor, but not necessarily loads induced by the rotor. The method is characterized in that the auxiliary connections between two adjacent annular sections are performed prior to stacking the following annular section.
