Is it also possible to also consider friction at nodal support in RFEM or RSTAB?


In both RFEM and RSTAB, it is possible to consider friction for the translation at nodal support.

You can select from different options that take into account the different directional components. For example, the friction force for the z‑direction can only be calculated from the y‑component or just from the x‑component, but also from both together or even from the addition of both forces.

In addition to the friction coefficient, you can also define the spring constant. It determines the behavior of the support before reaching the maximum friction force or the transition from static friction to sliding friction. The higher is the value of the spring constant, the less the support can deform before it changes to the sliding friction.
