Principia has carried out over 50 projects dealing with wind turbines, spanning the whole world: from India and China, to Mexico and Chile, including several European countries. Especially significant were the dynamic studies, under both wind-generated and seismic loads.
The objective of the studies varies with the project, but usually includes the foundation design, particularly when the ground may undergo problems such as seismic liquefaction. We have also investigated failures of towers and foundations, and we have contributed to the remediation of the problems detected.
Perhaps our more noteworthy projects are those that involve innovative structural designs, onshore and especially offshore, where the combined action of the wind and the waves fives rise to complex problems.
