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.
