Concrete strength evolution in WTG foundations

Optimized construction planning by leveraging numerical simulations to predict concrete strength evolution in onshore WTG foundations.

Rock-anchored WTG foundations

Rock-anchored foundations for onshore WTG can considerably reduce the required amount of concrete. The post-tensioned tendons help to resist the uplift forces mobilizing the surrounding bedrock.

Onshore wind turbine foundations

The basic principles that guide the design of WTG foundations, including the particularities of these structures.

Wind turbine vs. Windmill

Is a windmill the same as a wind turbine? Can you use those words interchangeably? Not quite! Let's see what are the key differences.

Wind Turbine Foundation Types

Overview of the main foundation types used in onshore and offshore wind energy projects.

Dense vs Sparse Matrix Storage in WTG Foundation FEM

In civil structures with beam elements, memory isn't usually an issue. But with solid elements for continuous systems, the stiffness matrix size explodes. Sparse matrix storage is the solution.

Quality finite element models

Finite element models must be meticulously verified before proceeding with further analysis. Follow these four steps in your finite element simulations to ensure accurate results.

Rock-anchored vs Shallow WTG foundations

Rock-anchored foundations for onshore WTG can reduce concrete volumes significantly. However, they require a strong, stable bedrock to resist considerably large stresses.

Slump test and massive wind turbine foundations

The slump test is a simple and straightforward method to assess the workability of fresh concrete. It remains widely used today, including in the construction of WTG foundations.

Automation with ANSYS APDL

Automate FEM tasks and finish them in seconds rather than hours. Learn how to parametrically export the results from an ANSYS simulation into a text file.

Cement hydration and high temperatures in WTG foundations

Cement hydration can generate significant heat in large structures like onshore WTG foundations. Internal temperatures can rise above safe levels, potentially leading to durability problems in the concrete.
