The consulting service dedicated to wind safety, on all terrain types
Estimate the wind to secure your projects
Wind is a powerful element, which means it is necessary to estimate its strength to ensure the safety of structures and transportation infrastructure. Whether it is a building, an electrical transmission tower, a roadway, a railway or a power line, our consulting service can meet your needs.
When designing a wind resistant structure, the classic option is to follow the Eurocode I, EN 1991-1-4. At each step of the design process, if there are any remaining doubts, the conservative approach tells you to choose the strongest design option. This results in oversizing your structures: overweight, overthickness, overpriced.
TopoWind allows you to get the optimal wind speed reference. This service is meant for project owners, engineering offices, control offices, urban planners, managers and the transportation industry.
Calculation of extreme wind speeds (fifty-year wind)
Extreme Wind modelling for equipment and infrastructure for transportation.
Calculation of roughness and orography coefficients according to Eurocode 1
Wind action on structures such as buildings, electrical towers or power lines.
The CFD technology
Thanks to our expertise in CFD technology, we can compute or simulate the wind on complex terrain to estimate roughness and orography coefficients as defined in Eurocode I. It is then easy to assess the extreme wind speed for a return period of fifty years.
We also offer a so-called storm method which makes it possible not to use the Eurocode. In this case, the 50-year wind is estimated by transferring the storm wind measurements collected at the weather stations to the project.
We calculate the local wind and its turbulence all around your project, taking into account the topography, meaning the relief and roughness of the environment (vegetation, buildings...).
We precisely compute the wind characteristics and extreme wind, even over large areas.
We also provide you with :
- The statistical distribution of wind speed and directions (compass rose)
- The vertical profile of the mean wind speed and turbulence intensity
A tailor-made solution
By keeping a conservative approach at each step of the process, this method gives the dimensioning reference of wind speed.
Therefore, the dimensioned structure will be adapted to the local wind conditions, while complying with wind safety standards.
The final design will be more economical, without excessive oversizing.
