We provide hints and tips to help you get started with the basic program RFEM.
Dynamic Calculations with Dlubal Software
Video
First Steps with RFEM
Description
Watch this video to learn more about the [RF-/DYNAM Pro] add-on modules for dynamic calculations of structures.
Utilize [RF-SOILIN] to consider soil-structure interaction. The further structural static analysis can then be carried out considering the dynamic analysis results in other add on modules. For example, you can perform fatigue designs for members with [RF-/STEEL Fatigue Members].
Dlubal Software offers structural engineers all necessary tools to perform dynamic calculations and the required ultimate limit state designs.

Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- Why do I only obtain the seismic loads calculated in one direction in the case of design with RF‑/DYNAM Pro?
- During the check in RF‑/DYNAM Pro, I get the message "No natural vibration case or dynamic load case has been selected for the calculation." Why?
- Is it possible to display natural frequencies separately for each direction?
- How can I enter or read out a response spectrum via the COM interface in DYNAM Pro?
- Is it possible to consider the second-order theory in a dynamic analysis in RSTAB?
- Why do I get large differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annex?
- How can I perform the stability analysis in RF‑/STEEL EC3 for a flat bar supported on edges, such as 100/5? Although the cross-section is rotated by 90° in RFEM/RSTAB, it is displayed as lying flat in RF‑/STEEL EC3.
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- How is the rotational stiffness of a buckling stiffener determined in PLATE‑BUCKLING?
