Pushover Analysis Software
The structural analysis software RFEM 6 is the basis of a modular program family. 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.
In RFEM, it is possible to determine a pushover curve or a capacity curve and export it to Excel.
This FAQ explains how to do this:
The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.
The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
The FC Campus ("Cube A" and "Cube B"), located directly at the A5 exit Karlsruhe-Nord, consists of two adjacent structural cubes at a slight offset, which leave a lasting impression due to their unique façade design.
The removable grandstands are surrounded on three sides by precast seating risers in the north endzone of the Los Angeles Football club soccer stadium. The grandstands are a free-standing system. The system is comprised of aluminum trusses, which are demountable from aluminum towers.
Palazzo Meridia in Nice is currently the tallest CLT office building in France. Dlubal customer CBS-Lifteam was responsible for the planning, supply, and installation of the timber structure.
This slender timber pedestrian bridge was constructed over the Bow River in Banff. At 13 ft wide and 38 ft long, the bridge is complete with a 263-foot clear span, which is perhaps the longest of its kind for a timber bridge.
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.
In December 2013, a hotel with extraordinary architecture opened in Davos, Switzerland. The building has the shape of 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.
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.
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.

Pushover analysis is a nonlinear structural calculation for the seismic analysis of structures. The load pattern is inferred from the dynamic calculation of equivalent loads. These loads are increased incrementally until global failure of the structure occurs. The nonlinear behavior of a building is usually represented using plastic hinges.
Different Natural Frequencies Without Consideration (left) and with Consideration of Tension Members (right)
Compared to the RF-/DYNAM Pro - Natural Vibrations add-on module (RFEM 5 / RSTAB 8), the following new features have been added to the Modal Analysis add-on for RFEM 6 / RSTAB 9:
- Preset combination coefficients for various standards (EC 8, ASCE, etc.)
- Optional neglect of masses (e.g. mass of foundations)
- Methods for determining the number of mode shapes (user-defined, automatic - to reach effective modal mass factors, automatic - to reach the maximum natural frequency)
- Output of modal masses, effective modal masses, modal mass factors, and participation factors
- Tabular and graphical output of masses in mesh points
- Various scaling options for mode shapes in the result navigator
