Question
Can I also use the wind load generator for open buildings?
Answer:
The load generator currently cannot generate loads for open buildings. You can create loads for a closed hall and then add the missing loads manually.
For canopy roof structures, there are different standard-based assumptions, which have not yet been covered by the load generator. To apply the wind load to a canopy roof, an interesting technical article is available on our website.
It is also possible to generate the wind load for any building geometry with the new stand-alone program RWIND Simulation. This provides you with possibilities for wind simulations
and wind load generation. You can use the options optimally in conjunction with the structural FEA software RFEM or the structural frame analysis software RSTAB.
Input
The direct import of models from RFEM or RSTAB allows you to define the relevant parameters for the analyzed wind directions with the height-dependent wind profiles, based on the wind standard. This results in the corresponding load cases with globally defined parameters.
You can also run RWIND Simulation manually without RFEM or RSTAB. Furthermore, it is possible to import the data from STL vector graphics.
The import of the terrain and buildings of the environment into the simulation is also possible from STL files.
By exchanging the data between RFEM or RSTAB and RWIND Simulation, you can easily use the wind analysis results as load cases in the usual RFEM or RSTAB work environment.

In Germany, DIN EN 1991-1-4 with the National Annex DIN EN 1991-1-4/NA regulates the wind loads. The standard applies to civil engineering works up to an altitude of 300 m.
In Germany, DIN EN 1991-1-3 with National Annex DIN EN 1991-1-3/NA regulates snow loads. The standard applies to civil engineering works at altitudes of up to 1,500 m above sea level.
In this article, the calculation of a timber panel wall with the beam panel thickness type is compared with a manual calculation.
Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.
The Concrete Design add-on for RFEM allows you to perform the fire design of reinforced concrete walls and slabs according to the simplified table method (EN 1992‑1‑2, Section 5.4.2 and Table 5.8 and 5.9).
When generating shear walls and deep beams, you can assign not only surfaces and cells, but also members.
In the Concrete Design add-on, you have the option to define an existing vertically oriented punching shear reinforcement. This is then taken into account in the punching shear design.
In RFEM, the oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".
