3.7.6: Reaction Forces 🔷

Fig. 3.7.6.1: Reaction forces and moments for two load-cases

The “Reaction Forces”-component gives access to the support forces and moments. It expects a model at its input-plug and returns via “RF” and “RM” a list containing reaction forces in $kN$ and reaction moments in $kN m$ as three dimensional vectors.

Specific supports can be selected via the "Pos|Inds"-input: either specify node indexes or positions. In case no input is provided, results for all supports will be output.

The input-plug “LCase” sets the load-case index for which the results shall be output. All support reactions are ordered in such a way that the indexes of the nodes they attach to form an ascending sequence. In case of locally oriented supports, reaction forces refer to the local coordinate system. “Pos” returns the position of the supports in the same order as the results. “SumRF” and “SumRM” offer the possibility to check the resultant reaction moments and forces of each load-case.
