Description
Reconstruction of Sailing Ship "Alexander von Humboldt II"
In October 2011, the sailing ship "Alexander von Humboldt II" started its service and has been conquering the seas ever since. The ship operated by German Sail Training Foundation (DSST) is a barque rigged with three masts. The masts and the hull consist of steel.

Find Mode Shapes From Critical Load Factor
The function, which is also known as shifting, allows you to calculate critical load factors beyond a user‑defined initial value.

Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
- 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 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?
- Is it possible to import effective lengths from RF‑STABILITY or RSBUCK in RF‑/TIMBER Pro?
- Where can I download the add-on modules, such as RF‑STABILITY?
- What is the critical load factor and how is it possible to determine it?
- How can I export the effective lengths from the RF‑STABILITY add-on module to Excel?
- How are the effective lengths of frame columns determined in RFEM or RSTAB?
