Im usig a fiber model with steel02 material. The response of the elements (forceBeamColumn) is recorded with basicDeformation recorder.
What I want to know is how can I compute the yield strain (or an approximation to it) with the mentioned material model.
Im asking this because computing the obious ratio fy/E=420/200000=0.0021 doesn't seem to be correct. For example for a beam of 9108mm the corresponding yield deformtion should be 0.0021*9108mm=19.1mm, but it seems to be about 13mm or 14mm.
the parameters of the material model are:
