Pushover Analysis Software
Structural FEM Analysis and Design
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.
Pushover Analysis
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:
Add-ons for Dynamic Analysis
For dynamic analysis, there are add-ons available for the determination of natural frequencies and mode shapes as well as for seismic analysis.
Interfaces for Data Exchange
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.

Determination of Pushover Curves
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.
New
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
- Which tools are available for a pushover analysis?
- Is the German National Annex 2021‑07 to Eurocode 8 available in RFEM 5 / RSTAB 8?
- Can I export a response spectrum from RFEM 6 and use it in RFEM 5, for example?
- How can I neglect masses in my modal analysis in RFEM 6 / RSTAB 9?
- Where can I adjust the standardization of a mode shape in RFEM 6 / RSTAB 9?
- How can I analyze the failure of an object, such as a column, in my modal analysis?
- Why do the results in a modal analysis differ between the initial prestress and the surface load?
- How can I display mode shapes in RFEM 6 and RSTAB 9?
- How can I perform an earthquake analysis in RFEM 6 and RSTAB 9?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
