70 wind turbines foundations for G90 T78m IEC IIIA model (initially designed for 100m height model)
Circular/octagonal geometry:16 m diameter
Piled or shallow foundations, built on site in a high seismic area
The report describes the calculations in order to prove the stability verifications, service or ultimate limit state verifications, and structural or additional verifications, according to Eurocode 0, Eurocode 2, Eurocode 3 and Eurocode 8 (including the essential checks about maximum pressure on soil, foundation overturning, foundation detachment from the soil, rotational stiffness, fatigue, etc.).
The works were based also on the wind turbine Manufacturer Loading Document and Client and Manufacturer Foundation Design Specifications.
