In addition to fatigue strength, the tower has to be resistant to extreme loads – buckling must not occur. The recognized international standards leave us with many options to verify the stability. With little effort we can produce results that lead to a satisfying solution. In our experience however, it pays off to look into the details when performing buckling analyses. We apply the most modern analysis methods and further develop them with partners in industry and science. This allows us to consider the actual strength of the material and make full use of the bearing strength of the design.
