Activating Internal Member Division for Stability Analysis

When analyzing structural elements susceptible to buckling by using the modules RF‑STABILITY (for RFEM) or RSBUCK (for RSTAB), it might be necessary to activate the internal division of members.

If there are, for example, truss members, these are not divided internally. Thus, a global failure shape is determined as the first mode shape in the stability analysis (see the image on the right). However, when activating the member divisions, it is clear that a local failure of the structure becomes decisive (see the image on the left). The image shows the option for activating the division in RF‑STABILITY.
