Dynamic and Seismic Analysis Software
FEM Analysis and Design of Structures
The structural analysis program RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
Analysis and Design of Beam Structures
The structural frame analysis and design program RSTAB contains a similar range of functions as RFEM, with special attention to frameworks. Therefore, it is very easy to use and for many years it has been the best choice for structural engineers.
Determination of Natural Frequencies and Mode Shapes
The RF-/DYNAM Pro - Natural Vibrations add-on module performs the analysis of natural frequencies and mode shapes.
Analysis of Forced Vibrations
The RF-/DYNAM Pro - Forced Vibrations add-on module performs the analysis of forced vibrations including the multi-modal response spectrum method and time history analysis.
Generation of Equivalent Lateral Loads for Earthquakes
The RF-/DYNAM Pro - Equivalent Loads add-on module generates equivalent lateral loads for earthquakes using the multi-modal response spectrum analysis.
Nonlinear Time History Analysis
RF-/DYNAM Pro - Nonlinear Time History is an extension of the add‑on modules RF‑/DYNAM Pro - Natural Vibrations and RF‑/DYNAM Pro - Forced Vibrations (linear time history analysis).
CADS Footfall Analysis
Footfall Analysis is post-processing software developed by CADS that can be used in conjunction with RFEM and RF-DYNAM Pro - Natural Vibrations provide footfall response analysis calculations.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.

With the RF-DYNAM Pro - Equivalent Loads add-on module, it is possible to generate automatically load distribution in accordance with a mode shape and export it as load case to RFEM.
- What method is applied in the RF‑/DYNAM Pro - Equivalent Loads add-on module?
- How can I display the results of the RF‑/DYNAM Pro add-on module in the printout report?
- In RF‑/DYNAM Pro, the "From self-weight of structure" option is available in a mass case. Is it always necessary to activate this option in order to consider the dead load of the structure?
- How can I adjust the number of decimal places in the standardized table values of a mode shape?
- I have used the RF‑/DYNAM Pro add-on module to generate the governing result combinations of seismic loads. What is the next procedure to perform the design of the individual structural components?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
- After the calculation in the RF‑/DYNAM Pro - Equivalent Loads add-on module, the size of my file has increased significantly. The performance has worsened enormously. What could be the reason for this?
- I would like to calculate and design "temporary structures." What do I need for this?
- Which programs can I use to calculate and design power plants?
- I noticed deviations from the map of DIN EN 1998‑1 or DIN 4149 in the online service "<a href="https://www.dlubal.com/en-US/solutions/online-services/snow-load-wind-speed-and-seismic-load-maps" target="_blank">Geo-Zone Tool: Snow, Wind, and Seismic Zone Maps</a>." Can you tell me which map is current and thus governing?
