When generating a wind load, are the vertical wall surfaces determined by area loads in an open building?


No, they are not included by default. The wind load generation executed via area loads always records the wind load orthogonally to the spanned surface.
For the attached example, however, Figure 2 shows that the loading in the wind load surface amounting 0.5kN/m² is relatively easy to convert.

However, it is also possible to generate the wind load for any given building geometry with the new stand-alone program RWIND Simulation. This provides you with the possibilities for wind simulations
and for generating wind loads. The possibilities can be optimally utilized in conjunction with the FEM structural analysis software RFEM or the structural frame analysis software RSTAB.

By directly importing models from RFEM or RSTAB, you can define 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.
