The RF-STABILITY add-on module determines the critical load factors, effective lengths and mode shapes of RFEM models. The stability analyzes can be carried out according to various eigenvalue methods, which have their advantages depending on the system and computer configuration.
- How does RF‑STABILITY or RSBUCK determine the buckling load? According to the manual calculation, the respective buckling loads should be about 10% higher.
- Why is it not possible to use result combinations in RF‑STABILITY? It is possible in RSBUCK indeed.
- How can I design any SHAPE‑THIN cross-section in detail in RFEM or RSTAB?
- I have calculated a pre-deformed structure according to the second-order analysis with RF-STABILITY and RF-IMP. Why are the deformations of the CO smaller than the applied pre-deformation?
- Is it possible to perform stability analyses on reinforced concrete structures by means of RF‑STABILITY?
- How can I perform a buckling analysis for a surface in RFEM?
How can I perform a stability/buckling analysis on a load-bearing structure?
- When determining the buckling modes in RF‑STABILITY, additional lines are displayed for each member perpendicular to the buckling curve. Why?
- Which modules are responsive via the COM interface RS‑COM or RF‑COM?
I have calculated the effective lengths in my model by using RSBUCK/RF‑STABILITY.Which effective lengths are relevant for further analyses?
