Abstract: It comprises a body that has an inertial asymmetrical and/or the body is asymmetrical in terms of geometry and/or mass of with respect to a XZ plane passing substantially through the centre of a wind turbine rotor for withstanding asymmetrical loads acting on the wind turbine. The inertia in sections of the structural member body at one side of the XZ plane may be 50% greater than the inertia in sections of the structural member body at another side of the XZ plane. The structural member may connect the wind turbine tower with the wind turbine rotor and may comprise at least two asymmetrical portions defined on both sides of the XZ plane which may be mutually asymmetrical reinforcing elements.
