Soil-Structure Interaction Analysis of a Wind Turbine Spread Foundation: a Case Study.

Resumo

Wind is a renewable source of energy, and its use occurs through the conversion of translational kinetic
energy into rotational kinetic energy, through the use of wind turbines to generate electricity. The present work
deals with the consideration of Soil-Structure Interaction (SSI) in a specific case of a wind turbine tower supported
on an “insulated footing” surface foundation. That said, a case study will be presented, which aims to analyze the
interaction of the wind tower foundation with the soil, verifying the use of additive materials to concrete, and the
SSI. To carry out the study, the computational tool, Diana FEA finite element modeling software, was used, which
allows the modeling and analysis of the structure by the finite element method. The results obtained in this work
allowed to enrich the discussion on soil-structural interaction.
