In the development of the script the API documentation for SAP2000 has been utilized to automate the modeling of the foundation. The foundation is modeled with thick
area elements to replicate the sloped geometry and properties of the foundation. FEM-analysis for different load cases was performed on the model in order to output sectional moments, normal and shear forces. The forces were used in order to design required reinforcement in the radial and tangential direction at the top and bottom edges of the foundation. This was performed with the sandwich model. Further, design of required shear reinforcement was incorporated into the script. As a result, the script outputs required reinforcement in tangential, radial and shear direction to guarantee structural integrity. Fatigue assessment was carried out using Markov matrices to verify that the cumulative damage of is below the value of 1.
The foundation design has not examined the impact of the anchor cage. Only simplifications of constraining it as a rigid body has been carried out. This implies that a more thorough analysis of the anchor cage’s impact on the foundation is necessary before relying fully on the script’s results.

- Climate change has heightened the focus on the renewable energy market. Initiatives aimed at reducing CO₂ emissions have made sustainable energy production one of today’s greatest challenges. The question of how to generate electricity sustainably has become a prominent political debate. Among the various approaches, wind turbines stand out, having recently undergone significant technological advancements. Despite the improvements, the expansion of wind power
lacks efficiency. Automating the modeling phase could be a key piece of the puzzle, enablingquicker production of drawings and dimensions for deployment.
