Determination of Pushover Curves in RFEM
Pushover analysis is a nonlinear static 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.
In RFEM, the plastic hinges according to the definition of FEMA 356 are available for the steel material. Together with the load increment option in RFEM and calculation diagrams, you can easily generate pushover curves.
3D Finite Element Analysis and Design
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.
In RFEM, it is possible to determine pushover curves (also called capacity curves) and export them to Excel.

Add-on Modules for Dynamic and Seismic Analysis
The RF‑/DYNAM Pro add-on modules allow for determination of natural vibrations, equivalent seismic loads, and so on.
