Determination of Pushover Curves
Tips & Tricks
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.
In RFEM, the plastic hinges according to the definition of FEMA 356 are available for the material of steel. Together with the load increment option in RFEM and calculation diagrams, you can easily generate pushover curves.

Frequently Asked Questions (FAQ)
- How is the plastic torsion determined in the plastic hinge definition?
- How can I get the member end forces to design the connections?
- I would like to calculate and design "temporary structures." What do I need for this?
- I cannot manage to correctly import the cross-section from a dxf file into the SHAPE‑THIN program, the imported cross-section is in a wrong plane. What can I do?
- How can I create a drilled beam in RFEM?
- How can I find out in which version of RFEM/RSTAB was the model saved?
- I have installed Rhino 7. When trying to export the model to RFEM, the data are not transferred. What do I wrong?
- I have already divided my membrane roof into individual surfaces. Can I quickly create a cutting pattern from these surfaces?
- I design timber components. The deformations of load combinations deviate from the manual calculation exactly by the factor of the material partial safety factor. Why?
- I often edit the reinforcement provided by the program. Adjusting the reinforcement by using coordinates takes much effort and time if having several beams in the model. Is there any way to speed up the reinforcement editing?
