Method for assembling a wind turbine, wherein the wind turbine comprises a tower, a nacelle and a rotor, the tower comprising stackable annular sections (3, 4, 5, 6), wherein the method comprises the following steps: - stacking, upon a first annular section, a second annular section, by using lifting and positioning means; - performing auxiliary connections for connecting the first and the second annular sections to each other by using auxiliary connecting means, wherein the auxiliary connections are performed prior to stacking a third annular section or another wind turbine component upon the second annular section, wherein the auxiliary connections are further configured to withstand seismic loads induced by an earthquake; wherein for performing the auxiliary connections, the first annular section comprises housings, located in an upper flange of the first annular section, and the second annular section comprises bars emanating at least from a lower flange of the second annular section, wherein the housings of the first annular section are configured to allocate the bars of the second annular section, for defining bar -housing assemblies wherein the bars are inserted into the housings; and characterized by: - the step of performing the auxiliary connections comprises partially filling with resin only some of the housings, wherein a step of performing main connections for connecting the first annular section and the second annular section to each other comprises completing the filling of the housings that already comprise resin with grout and filling with grout the housings that have not been filled with resin; or wherein - the step of performing the auxiliary connections comprises partially filling with resin all the housings, wherein a step of performing main connections for connecting the first annular section and the second annular section to each other comprises completing the filling of the housings that already comprise resin with grout. - stacking, upon a first annular section, a second annular section, by using lifting and positioning means; - performing auxiliary connections for connecting the first and the second annular sections to each other by using auxiliary connecting means, wherein the auxiliary connections are performed prior to stacking a third annular section or another wind turbine component upon the second annular section, wherein the auxiliary connections are further configured to withstand seismic loads induced by an earthquake; wherein for performing the auxiliary connections, the first annular section comprises housings, located in an upper flange of the first annular section, and the second annular section comprises bars emanating at least from a lower flange of the second annular section, wherein the housings of the first annular section are configured to allocate the bars of the second annular section, for defining bar -housing assemblies wherein the bars are inserted into the housings; and characterized by: - the step of performing the auxiliary connections comprises partially filling with resin only some of the housings, wherein a step of performing main connections for connecting the first annular section and the second annular section to each other comprises completing the filling of the housings that already comprise resin with grout and filling with grout the housings that have not been filled with resin; or wherein - the step of performing the auxiliary connections comprises partially filling with resin all the housings, wherein a step of performing main connections for connecting the first annular section and the second annular section to each other comprises completing the filling of the housings that already comprise resin with grout. - the step of performing the auxiliary connections comprises partially filling with resin only some of the housings, wherein a step of performing main connections for connecting the first annular section and the second annular section to each other comprises completing the filling of the housings that already comprise resin with grout and filling with grout the housings that have not been filled with resin; or wherein - the step of performing the auxiliary connections comprises partially filling with resin all the housings, wherein a step of performing main connections for connecting the first annular section and the second annular section to each other comprises completing the filling of the housings that already comprise resin with grout.
