FAQ 004131 EN

How do I determine wind loads on structures of any shape?

Answer

The new standalone program RWIND Simulation provides you with the options for wind simulation and for generating wind loads. The options can be optimally utilized in conjunction with the FEM structural analysis software RFEM or the structural frame analysis software RSTAB.

Input

The direct adoption of models from RFEM or RSTAB makes it possible to determine relevant parameters of the wind directions to be analyzed with height-dependent wind profiles on the basis of a wind standard. This results in the corresponding load cases with globally defined parameters.

The RWIND Simulation can also be run manually if there is no RFEM or RSTAB. For this reason, the data can be imported from STL vector graphics.

The import of terrain and buildings of the environment into the simulation is also possible from STL files.

By exchanging data between RFEM or RSTAB and RWIND Simulation , you can easily use the wind analysis results as load cases in your usual RFEM or RSTAB work environment.
