Piled foundations supporting tall wind turbines are subjected to inclined and remarkable eccentric loads during their life span due to extreme wind conditions. A novel, exact solution for failure envelopes of pile groups under combined axial-moment load based on theorems of limit analysis is presented and discussed. The attention is then placed on the results of an intense centrifuge program aimed at validating the above solution. The focus is set finally on a recent, physically motivated mathematical framework for settlements and rotations prediction of piled foundations under eccentric load. The new concepts and ideas emerging from this research may lead to tangible and intangible advantages in the field of renewable energy industry.
