Support Reaction

Glossary Term

A support reaction can be a force resulting on a support or a resulting restraining end moment, which results due to a prevented possibility to move.

In the case of structural systems, support reactions are in equilibrium with the external forces acting on the structure. The resulting support reactions and the external loads are opposed to each other and theoretically result in zero.

Support Reactions in RFEM and RSTAB

In RFEM and RSTAB, it is possible to evaluate support reactions graphically or in tables. For the individual load cases and combinations, the deviations from the sums of acting loads can also be checked in addition to the sums of support forces.
