It is possible to select whether it is a sharp-edged eaves area, an eaves area with attic, a rounded eaves area, or a beveled eaves area. Then, the corresponding loads are applied according to EN 1991‑1‑4 Table 7.2.
Consideration of Eave Area Formation when Generating Wind Load
In addition to the geometry and shape of a flat roof, you can also take into account the formation of an eaves area when generating the loading.

Since wind on laterally open structures is not addressed in the Eurocode, the 4 cases of the German DIN 1055, Part 4 are referenced.
Structures react differently to wind action depending on stiffness, mass, and damping. A basic distinction is made between buildings that are prone to vibration and those that are not.
In addition to the geometry and shape of a flat roof, you can also take into account the formation of an eaves area when generating the loading.
The automatic creation of combinations in RFEM and RSTAB with the "EN 1990 + EN 1991‑3; Cranes" option allows you to design crane runway beams as well as support loads on the rest of the structure.
There are load generators available for beam structures, creating snow loads according to ASCE/SEI 7-10. The load cases are generated depending on the roof shape. Another generator creates coating loads (ice). You can save recurring load combinations as templates.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
