3.6.5: Reaction Forces 🔷

Fig. 3.6.5.1: Beam under axial & transverse point-loads: Reaction forces and moments for both load-cases

The “Reaction Forces”-component gives access to the reaction forces and moments at supports. 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. 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.
