[REQUEST] Onshore wind turbines

[justas1986]

Hello all,

I am researching and designing the onshore wind turbine foundation and its behaviour on soils (Influence of wind turbine foundations action on soils) and would like to ask some advices and recomendations.

Maybe could anybody to recomend and advice some literature or give other information where i could to find:
- about wind loads and its influence for foundation (dynamic loads);
- about natural frequency of construction and its evaluation;
- about soils characteristics and its evaluation (dynamic modulus of stiffness and etc.);
- about designing of foundations and etc.

All information is useful for me about onshore wind turbines.

Many thanks for help.
