Activating Internal Member Division for Stability Analysis
Tips & Tricks
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. In this way, a global buckling mode is determined as first eigenvector in the stability analysis (see Picture 1). When activating the member divisions, we see that a local buckling of the structure is governing (see Picture 2). The figure shows the option for activating the division in RF‑STABILITY.
