Pushover Analysis Software
Structural engineering FEA software RFEM is the basis of a modular software system. 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 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 monastery "Little Flower" 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 as well as 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 has been the first project carried out in wood.
The multigenerational house with a view at Lake Constance was built as an environmentally friendly wooden structure and designed as a passive house.
The Dlubal Software customer Pirmin Jung Ingenieure from Sinzig, Germany, was in charge of the structural and dynamic analysis.
Butadiene storage tanks of the French company ARLANXEO Emulsion Rubber France, one of the biggest producers of synthetic rubber NBR in the world, had to be recalculated to comply with the seismic requirements of Eurocode 8.
In December 2013, a hotel with extraordinary architecture was opened in Davos, Switzerland. The building has the shape of a “Golden Egg” and is situated on a mountainside.
The hotel is elliptic in shape with all corners rounded out 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 34 m and a height of 30 m.
One of the world's highest timber structures is a look‑out tower on the Pyramidenkogel, a mountain in Carinthia, Austria.
The spiral-shaped tower with a height of 100 m provides a breathtaking view over the Alps-Adriatic region.

Pushover analysis is a nonlinear structural calculation for seismic analysis of structures. The load pattern is inferred from dynamic calculation of equivalent loads. These loads are incrementally increased until the global failure of the structure occurs. The nonlinear behaviour of a building is usually represented by using plastic hinges.
Different Natural Frequencies Without Consideration (left) and with Consideration of Tension Members (right)
The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.
- Which tools are available for a pushover analysis?
- 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?
- How do you distinguish between the response spectra with equivalent loads and the response spectra without equivalent loads in RFEM and RSTAB?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
- Why do I only obtain the seismic loads calculated in one direction in the case of design with RF‑/DYNAM Pro?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
