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. However, when activating the member divisions, it is clear that a local failure of the structure becomes decisive.
