What is it about?
Plastic hinges properties, for use in static pushover analysis, can be modified as a function of ductility demand. This way it is possible to account for damage (represented by ductility demand) in the analysis of subsequent eaqrthquakes.

Why is it important?
The modificatiobn factors are calibrated on tests performed on non conforming RC elements
