Is it possible to only enter a half of a symmetric structure? It would facilitate the modeling and speed up the calculation.


In RFEM and RSTAB, it is not possible to use the symmetry of the structure to calculate only a half of the structure.

However, it is possible to create only a half of the structure including the loads and then to generate the other half by using the menu tool "Edit → Select → All" and then "Edit → Mirror." In the Mirror dialog box, it is necessary to select the "Create copy" option and the "Copy including loading" option under [Details] (see Figure 01).

In this way, you can omit the supports in the mirror axis and obtain more realistic results.
