Abstract
ENGLISH ABSTRACT: Transportation logistics of large steel towers have led to concrete towers becoming a viable option. There are currently no design codes dealing exclusively with the design of concrete
wind turbine towers. Wind turbine towers have strict constraints on the fundamental frequency
of the tower to avoid resonance. This paper investigates the dynamic behaviour of wind
turbine towers using nonlinear finite element modelling. Focus is placed on the effect of crack
formation and soil stiffness on the fundamental frequency of the tower. An analytical model is
then proposed that can be used in the primary design stage to determine the geometry of the
tower that satisfies the fundamental frequency requirements.
