Question:
Is it possible to only enter half of a symmetric structure? It would facilitate the modeling and speed up the calculation.
Answer:
In RFEM and RSTAB, it is not possible to use the symmetry of the structure to calculate only half of the structure.
However, it is possible to create only half of the structure including the loads and then generate the other half 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).
This way, you can omit the supports in the mirror axis and obtain more realistic results.
