Midas Webinar:

Cyclic and Monotonic Behavior of Onshore Wind Turbine Foundation Systems in Cohesionless Ground

(PDH Certificate)

Thursday, May 26, 2022, 2:00 PM - 3:00 PM EDT





The wind turbine foundation design is complex due to the large cyclic loading demands. Thus, investigation of the monotonic and cyclic behavior of wind turbine foundation systems is necessary to ensure safe and cost-effective design.


During this webinar, MIDAS Expert Engineer Osvaldo Vitali will provide us with an insight into the behavior of different wind turbine foundation systems under complex loading conditions. The gravity foundation system (GFS) and the tensionless pier system with reinforcing collar (TPC) and without reinforcing concrete collar (TP) are examined. The 3D FEM modeling was conducted. An advanced constitutive model capable of capturing the cyclic and the monotonic behavior of cohesionless soils was adopted. The results from this study demonstrates that the TPC has a superior performance in maintaining the serviceability requirements under large load demands. Osvaldo and his colleagues published this paper at the conference proceedings of Geocongress2022 using GTS NX.


Engineers will be able to follow along throughout the entire session. At the end of this session, engineers will also have the opportunity to ask questions, whether it be about the process or the software itself. We will be offering PDH certification for this course for engineers who attend the full session. This webinar is only for North American engineers. 


Osvaldo Paiva Magalhaes Vitali - Geomechanics Engineer at BRASKEM S/A


Dr. Osvaldo Vitali is a geomechanics engineer at BRASKEM S/A, post-doc associate at the University of São Paulo, and Early Carrier Editor (ECEB member) at the Underground Space journal. He holds a Ph.D.in Civil Engineering from the Lyles School of Civil Engineering at Purdue University, M.Sc. in Geotechnical Engineering, from the University of São Paulo, and B.Sc. in Civil Engineering from the State University of São Paulo. Dr. Vitali joined Purdue University in January 2016 after obtaining a very prestigious scholarship for doctoral students from the Brazilian Government. During his Ph.D. program, he has published ten articles and three conference papers, as the first author, in four years. The results of his Ph.D. research have significant practical applications and will ultimately contribute to improving predictions of tunnel response ahead of the tunnel face, based on the performance of the tunnel already excavated.

Before joining Purdue University, Dr. Vitali worked for five years at THEMAG Engenharia, São Paulo, Brazil, on designing large Infrastructure projects, especially tunnels and deep excavations in urban environments. Among other tasks, he was responsible for conducting 3D FEM modeling of complex geotechnical structures in soil masses, such as tunnel-shaft connections, and assessing the impacts of tunnels and deep excavations on adjacent structures. After the Ph.D., he worked for one year at Terracon Consultants Inc, Germantown, MD, USA, designing and investigating the behavior of wind turbine foundation
