- the distribution can be determined or estimated, for example, by wind measurements and / or recorded control data.
- stress collectives for the design life can be determined. While in existing design methods the design is made against the stress collective of the main load direction, assuming that this load acts over the entire planned life from the main load direction, the method according to the invention provides for taking into account the distribution of the occurrence of the load over different load directions. For this distribution, a probability density, for example described over the circumference of the tower construction, is preferably used. In this case, the highest probability of the main load direction is preferably assigned. Depending on the probabilities over the circumference of the tower structure, for example, steps of a stress collective of the main load direction can be distributed over the circumference or a part of the circumference (depending on the probability density).

- the operating loads originally determined for the design of the tower structure for example in a simulation, can be used and modified with the method according to the invention.
- measurement data from wind measurements and / or operational management data of the wind energy plant can also be taken into account.
- the considered wind means usually also affects the load collective.

It can be seen that in the main load direction of 90 °, the largest proportion is recorded and in the adjacent Maubelastungsschen of 80 ° and 100 ° the next larger proportions are recorded, whereas for the Maubelastungsraumen of 70 ° and 1 10 ° already significantly smaller Shares are to be recorded. The remainder R is distributed over the further secondary load directions.
- the distribution used for this purpose, shown in FIG. 4B is a Gaussian normal distribution with an expected value of 90 ° and a variance of 180 °. On the vertical axis, the frequency is recorded in the reference period (the lifetime), and on the horizontal axis the position on the circumference of the tower is in degrees of arc.
- FIG. 5 shows distributions V0, V30, V60, V90, V120, V150, V180 of the occurrence for different load directions, here simplified in 30 ° steps. Also simplified here is the same Gaussian distribution with an expected value of 90 ° and a variance of 180 ° basis. However, different distributions for different load directions can be assumed.
