This thesis depicts the effects and consequences of simplifying time-varying loads to equivalent static loads acting on a finite element modelled wind turbine tower. The structural response is assessed with respect to structural stability behaviour. Limit load buckling, inertia affects, and geometrical nonlinearities are central topics in this thesis. The limit load buckling behaviour of a simple truss under static and time-varying loads is presented at first, and findings are used for further analysis of a wind turbine tower. The analysis of a wind turbine tower is initiated with an examination of the structural response with different simple time-varying load types and combinations. Combinations of real wind loads are applied to the tower, and relations between load magnitude and duration are found.
