SUMMARY:

Wind energy is becoming increasingly relevant in the energy landscape, as one of the main renewable energy alternatives to meet the growing global energy demand. One of the main challenges in the construction of wind turbines for energy production is the foundation project that must satisfy the economic and structural requirements of the project. Shell structures, little explored as foundations for wind turbines, can present themselves as a structural and economically more efficient alternative than flat structures. In this context, the present study aims to analyze the structural and geotechnical behavior of conical shells used as foundations in onshore wind turbines, through numerical analysis using the ANSYS software, based on the Finite Element Method (FEM). For this analysis, a case study was carried out in a wind farm located in Campo Formoso, Bahia. Numerical models representative of the conventional foundation, used in the case study, and of the foundation in shell will be developed, adopting the constitutive Mohr-Coulomb model. With the results obtained, it is expected to analyze the structural and geotechnical behavior of the shell foundations in comparison to the conventional foundation used in the case study.
