Generating LC from RC

A result combination (RC) combines results from the selected load cases (LC), load combinations (CO), and result combinations according to a preset combination syntax. Since a particular result may show an extreme value, depending on the combination at various locations of the structure, the RC displays the maximum and the minimum values for each result type.

The extreme result values are generated from the superimposition of different LC, CO, and RC results, taking into account the partial factors set previously. There is a corresponding combination syntax for practically every extreme value.

Right‑click any extreme value in the table and select "Generate CO Acc. to Selected Row" or "Generate CO Acc. to Selected Cell" to generate a new load combination (CO) with the corresponding combination syntax. This CO is adjusted to the linear static analysis by default and named after the selected extreme value.

The calculation of this CO provides the selected extreme value at the corresponding location, as well as the relevant internal forces on all the other elements.

In RFEM, the generating function is available in the following tables:
4.1 Nodes – Support Forces (values, extreme values)
4.3 Line Support Forces (extreme values)
4.4 Members – Local Deformations (extreme values)
4.5 Members – Global Deformations (extreme values)
4.6 Members – Internal Forces (values, extreme values)
4.7 Members – Contact Forces (extreme values)
4.8 Member Distortions
4.12 Cross‑Sections – Internal Forces (values, extreme values)
