Structure Stability

How do I perform stability analysis to determine the critical load factor in RFEM 6?


Answer:

1) Activate the Structure Stability add-on in the Base Data (Image 01)

2) Adjust the Stability Analysis Settings as required (Image 02)

3) Activate the Consider Stability Analysis option in the Load Cases & Combinations for the required load cases and combinations. You may need to switch to Geometrically Linear analysis to run the stability analysis if the structure is unstable under second order analysis (Image 03)

4) After solving the selected load combinations, the critical load factors can be viewed in the Stability Analysis table (Image 04)
