| Abstract | The grouted transition piece is connection which to connects a monopile foundation to the wind turbine tower through a transition piece. There are many parameters which affected to the capacity of offshore wind turbine grouted transition piece. The length of grouted connection is one of them. It affected to the bond between steel tube and grout, due to friction, adhesion and roughness of the contact interface. This research describes the influence of grouted length on two shapes of grouted transition piece for offshore wind turbines under uniformly axial load and pure bending load. XFINAS 3-D finite element analyses have been carried out for this parametric study. It is shown that grouted length has significant effect on capacity of wind turbine structure especially in initial state. An increasing of the grouted length led to higher capacity of the structure. Furthermore, conical shape can produce performance of model under uniformly axial load higher than cylindrical shape. On the other hand, for the model under pure bending, cylindrical shape has capacity higher than conical shape. In detail comparison results of each case are presented in this thesis |
