Dynamic and Seismic Analysis Software
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.
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.
The RF-/DYNAM Pro - Natural Vibrations add-on module performs the analysis of natural frequencies and mode shapes.
The RF-/DYNAM Pro - Equivalent Loads add-on module generates equivalent lateral loads for earthquakes using the multi-modal response spectrum 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).
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.
The "Little Flower" monastery was built in 2015, situated in beautiful scenery of green meadows, mountains, and crystal-clear lakes.
The little monastery is equipped with 18 bedrooms, a chapel, a dining room, a kitchen, and a conference room.
A timber apartment complex with appealing architecture has been built in the Italian town of Brescia. Four housing complexes include a total of 72 housing units.
For the Lombard Institute for Residential Buildings (ALER), this was the first project carried out in wood.
The multigenerational house with a lakeside view was built as an environmentally friendly timber structure and designed as a passive house.
The engineering office Pirmin Jung Deutschland GmbH, a customer of Dlubal Software, was in charge of structural analysis, among other things.
The butadiene storage tanks of the French company ARLANXEO Emulsion Rubber France, one of the biggest producers of NBR synthetic rubber in the world, had to be recalculated to comply with the seismic requirements of Eurocode 8.
In December 2013, a hotel with extraordinary architecture opened in Davos, Switzerland. The building is shaped like a golden egg and is situated on a mountainside.
The hotel is elliptical in shape with all corners rounded, and is constructed with reinforced concrete.
An extraordinary structure was built in Chile: "Temple of Light", one of eight Bahá'í temples in the world.
The shape of the temple resembles a nine‑petalled blossom of a lotus flower. The building has a diameter of about 111.5 ft and a height of 98.4 ft.
One of the world's highest timber structures is a lookout tower on the Pyramidenkogel, a mountain in Carinthia, Austria.
The spiral-shaped tower with a height of 328 ft provides a breathtaking view over the Alps-Adriatic region.

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?
