In RFEM, forces and moments can be introduced into the model as line loads. They are usually entered as a force per unit length (for example, kip/ft), and it is also possible to define a concentrated line load of the line at any location. Furthermore, there is also the possibility to apply line loads varying over the length.
The line load can only be considered if the line is a part of a surface. Thus, the line load cannot be applied to a member lying outside a surface. For this, it is necessary to use a member load.
The line load in its effect can be related to the local or the global axis system. When using the local axis system, rotation of the line load is possible.
Entering in RFEM
Line loads can be entered and defined in RFEM and RSTAB graphically by clicking "Insert" → "Loads" → "Line Loads" → "Graphically" or the corresponding toolbar button, or by using tables.

The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
- I would like to calculate and design "temporary structures." What do I need for this?
- Which programs can I use to calculate and design power plants?
- In the filter settings for the values on surfaces, you can display a certain range of results and hide the rest. How can I hide a certain range of values and display the rest?
- What is the best way to consider steel fiber reinforced concrete with the structural analysis program RFEM?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- Does a user-defined layer composition in RF-LAMINATE need to be shared separately with other users along with the RFEM model file or is this information stored directly in the RFEM file?
- I have modeled two nodes on a surface in RFEM. The results do not show the displacement at these two nodes. How can I obtain it?
