摘要：Fatigue is the significant factor resulting in the failure of the support structure for an offshore wind turbine (OWT) subjected to combined hydrodynamic loads and aerodynamic loads. The tubular joints are the weakest component leading to fatigue failure of the whole structure. But in current fatigue assessment method, the effect of torque loading applied on brace component is neglected. Considering the multi-pile foundation structure which is used widely in China, a three-planar tubular Y-joint as the connection between diagonal braces and central column of a typical tripod OWT substructure is selected to study the influence of torque loading on fatigue life. The study mainly focuses on three levels as follows: component internal stress analysis, the stress concentration factor (SCF) and the fatigue damage of OWT.
