title = "Simplified model for offshore wind turbines with variable cross-section towers",
abstract = "In this study, a rigid-base single-degree-of-freedom structural model was proposed for the wind turbine with a linearly variable cross-section tower. Additionally, the concentrated spring model was introduced to simulate the flexibility of grout connection at the transition piece as well as the monopile foundation for structural modelling of an offshore wind turbine. Thus, the close-form solution of its natural frequency was accordingly obtained and was verified satisfactory. This simplified model was then used to exhibit the influence of the grout connection failure and the foundation scour on the natural frequency of wind turbine structures, showing its applicability to damage detection.",
