In RFEM, plastic hinges according to the definition of FEMA 356 are available for steel material. You can easily generate pushover curves with the load increment option in RFEM and calculation diagrams.
Determination of Pushover Curves
Pushover analysis is a nonlinear structural calculation for 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 behaviour of a building is usually represented by using plastic hinges.

This article will show you how to model and design cable structures in RFEM 6 and RSTAB 9.
This article shows and explains the influence of the bending stiffness of cables on their internal forces. This article also gives hints on how to reduce this influence.
The ASCE 7-22 Standard [1], Sect. 12.9.1.6 specifies when P-delta effects should be considered when running a modal response spectrum analysis for seismic design. In the NBC 2020 [2], Sent. 4.1.8.3.8.c gives only a short requirement that sway effects due to the interaction of gravity loads with the deformed structure should be considered. Therefore, there may be situations where second-order effects, also known as P-delta, must be considered when carrying out a seismic analysis.

The deflection due to the normal compression forces shown in (a) is (b) converted into equivalent moments of displacement or shear forces [2].](/en/webimage/009762/2420261/01-en-png-12-png.png?mw=350&hash=dd36dc43123116724231958668ad6cdcb13a0169)
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
How is the plastic torsion determined in the plastic hinge definition?
I cannot activate the Cutting Patterns add-on. What is the reason?
I cannot activate the Timber Joints add-on. What is the reason?
Has the RFEM 5 module RF-TOWER already been implemented in RFEM 6?
The performance when starting the programs or working in the program has become noticeably worse. What could be the cause of this?
Is it possible to influence the transverse distribution of a load in the case of the Isotropic | Masonry | Plastic material model?
