The size of an RFEM or RSTAB file depends on the model size. This is, in turn, dependent on the number and size of the individual model data.
Entering in RFEM and RSTAB
When RFEM or RSTAB is opened, you can create a new model by clicking the list button "New Model" oder "File" → "New." Besides entering the description of the model, you can define the basic settings in the "New Model - General Data" dialog box, such as the type of model. A 2D model can only be drawn in one plane and has three degrees of freedom, whereas a 3D model has six degrees of freedom and all three work planes XY, XZ and YZ are available.
There are different display types available for the model, also called rendering:
- Wireframe model: In the wireframe model, only the axes of members (and surfaces) are displayed linearly.
- Solid model (transparent/filled): In the solid model, the objects are displayed in the original form, that is including their cross-section.
To adjust the setting, use the 'Display Model' list button or the Project Navigator "Display" → "Rendering" → "Model."
It is also possible to generate typical models or partial models automatically by entering all necessary parameters. Open the model generator via "Tools" → "Generate Model - Members (in RFEM, also surfaces)."
Depending on stiffness, mass, and damping, structures react differently to wind action.
- How can I model a timber-concrete composite floor?
- Is it possible to parameterize models and loads with RFEM and RSTAB?
My license does not work, what can I do?
- Why is there no support force displayed even though I have modeled the member foundation?
- RFEM calculates all load combinations automatically according to the second-order analysis. Is it possible to deactivate this?
- Is it possible to change the font size of dimensions?
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
- I would like to calculate a multi-span beam. Is it possible to automatically apply imposed loads by span (for the design of the largest supporting moment and moment in the span)?
- How the shear deformation of a member can be taken into account?
