First Steps with RFEM
Description
Buildings are structures surrounded by wind. The flow around them creates specific loads on the surfaces, which are to be used for the design in structural analysis.

Wind Flow on Laterally Open Structures According to DIN 1055-4
Since wind on laterally open structures is not addressed in the Eurocode, the 4 cases of the German DIN 1055 Part 4 are referenced.
RWIND 2 | Transfer of Wind Loads to RFEM or RSTAB
When you start the analysis in the application of RFEM or RSTAB, a batch process starts that places all member, surface, and solid definitions of the model rotated with all relevant coefficients in the numerical wind tunnel of RWIND Basic, starts the CFD analysis, and returns the resulting surface pressures for a selected time step as FE mesh nodal loads or member loads into the respective load cases of RFEM or RSTAB.
These load cases which contain RWIND Basic loads can be calculated and combined with other loads in load combinations and result combinations.
- How do I create a user-defined Design Situation with my own chosen load combinations?
- How do I create a frame joint with taper in JOINTS Steel - Rigid?
- I would like to extend an existing structure with a false ceiling that is not connected to the existing columns. How can I model it?
- For line releases, I obtain the resultants in the horizontal direction, which I cannot understand.
- How can I display wind speeds at a certain height above the ground for a wind comfort analysis?
- Can I also use the wind load generator for open buildings?
- When evaluating the support reactions of a plate supported by line supports, I noticed that the support reaction pz' does not correspond to the shear force and deviates significantly. Why?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
- What is the meaning of the "Activate Weld Design" option in the detailed settings of RF‑/STEEL EC3?
- Why do I obtain different results for the same end plate joint in RF‑/JOINTS Steel - DSTV and RF‑/JOINTS Steel - Rigid?
