- The height of a real wind turbine tower structure is far larger than the length in the plane, so segmented assembly is generally adopted on the spot. However, after assembling a tower, annular ribs for blocking concrete and connecting tubes of a double-layered steel tower in the construction of the tower sections remain in the tower structure. These annular ribs can influence mechanical performances of the tower, so the research is very important. The calculations of finite element models with no ribs and with annular ribs and longitudinal ribs show that the annular ribs used during the segmented assembly slightly affect flexibility of the tower before yielding. However, they have great influences on stress in the inner and outer steel tubes in the compressive zone under the constraints of concrete. Furthermore, concrete slightly constrains longitudinal deformation and shows no obvious effect on flexibility of the tower and stress in the inner and outer steel tubes. The variation of loading direction cannot change the influences of the longitudinal ribs on the tower.
