A double‑mass system consists of two shafts and two masses represented by the corresponding moments of inertia, concentrated in a given distance as nodal masses. The left shaft is fixed, and the right mass is free. Neglecting the self‑weight of the shafts, determine the torsional natural frequencies of the system.

This article describes and explains the influence of bending stiffness of cables on their internal forces. Furthermore, the text provides information on how this influence can be reduced.
This article provides a detailed overview of the export features from RFEM 6 and RSTAB 9 to AutoCAD/DXF files, including options for exporting dimensions, FE meshes, and deformed shapes.
This article provides a detailed overview of the import features from RFEM 6 and RSTAB 9 to AutoCAD/DXF files.
This technical article addresses the direct deformation analysis of reinforced concrete beams considering the long-term effects of creep and shrinkage. The direct calculation according to Eurocode 2 (EN 1992-1-1, Section 7.4.3) is explained using a single-span beam. Particular emphasis is placed on tension stiffening, behavior in the cracked state based on the distribution factor (damage parameter), and consideration of shrinkage and creep behavior.
In the Snow Load Wizard, you can optionally consider snow overhang and snow guard when generating snow loads according to Eurocode.
The Construction Stages Analysis (CSA) add-on allows you to modify the object and design properties of members, surfaces, and so on, in the individual construction stages.
During the calculation, you can display the model deformation for the calculation steps graphically in the calculation progress window.
In the wind simulation, it is possible to consider member coatings (for example, from ice loads).
For my NVIDIA graphics card, I need to select between a driver from the "Production Branch" and a "New Feature Branch." Which driver is best suited for RFEM/RSTAB?
Is it possible to quickly evaluate whether the mesh used is fine enough?
Why do the min/max values of the total displacement not match the deformations when working with result combinations?
Does RFEM 5 include a surface contact?
Can I display node coordinates in my model?
Has the RF-TOWER add-on module for RFEM 5 already been added to RFEM 6?
