Question
I just have to calculate an open hall with low roof loads and, compared to them, relatively high wind loads. In theory, it is necessary to perform the lateral-torsional buckling design of the bottom flange. Unfortunately, the combination 1.0*G + 1.5*W is missing.
Answer:
Additional combinations of favorable permanent actions can be considered using the Combination Expressions window in RFEM / RSTAB (see Image 01) and Window 1.4 in RX‑TIMBER (see Image 02).

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.
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".
In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
