Time-History Analysis in RFEM - Induced Vibrations
Free Online Seminar
Periodically, structures subjected to machine induced vibrations or blast loading require a dynamic analysis. A powerful yet intuitive structural analysis software is essential for these scenarios.
- Overview and features of RFEM and the dynamic add-on modules
- Natural frequency analysis utilizing RF-DYNAM Pro – Natural Vibrations
- Time-history analysis utilizing RF-DYNAM Pro – Forced Vibrations

The effects due to snow load are described in the American standard ASCE/SEI 7-16 and in Eurocode 1, Parts 1 through 3. These standards are implemented in the new RFEM 6 program and the Snow Load Wizard, which serves to facilitate the application of snow loads. In addition to this, the most recent generation of the program allows the construction site to be specified on a digital map, thus allowing the snow load zone to be imported automatically. These data are, in turn, used by the Load Wizard to simulate the effects due to the snow load.
For the joint components, it is possible to check whether the stability failure is relevant (requires the Structure Stability add-on for RFEM 6 / RSTAB 9).
In this case, the critical load factor for all analyzed load combinations and the selected number of mode shapes is calculated for the connection model. The smallest critical load factor is compared with the limit value 15 from the standard EN 1993‑1‑1, Clause 5. Furthermore, a user-defined adjustment of the limit value is possible. Moreover, the corresponding mode shapes are displayed graphically as the result of the stability analysis.
For the stability analysis, an adapted surface model is used to specifically recognize the local buckling shapes. The model of the stability analysis, including the results, can also be saved and used as a separate model file.
- Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- How can I optimize cross-sections within the steel design?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- How do I apply wind load on members of open structures?
- Is it also possible to use RF‑/TOWER Loading without the other TOWER add-on modules?
- I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
- I have a roof structure resting on a steel column that runs to the foundations. The column runs through a perimeter wall that supports the false ceiling. A considerable part of the load from the roof is transferred to the wall. I want the steel column to carry all the vertical loads from the roof. How can I do it?
- Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
- I encountered a sharing violation while importing a dxf file into SHAPE-THIN. What is the issue?
