Hysteretic material reference

[cchisari]

Dear all,

I would like to understand (and report in a paper) the exact formulation of the degradation rules for the Hysteretic material.

Unfortunately, no academic reference is provided in the manual (expect for the qualitative aspects shown in http://opensees.berkeley.edu/OpenSees/m ... l/4052.htm) and I am not able to formulate these rules reading from the source code.

Please can anyone help me with any reference?

Thank you and best regards,

cchisari

I also have the same question. But I think the best way is to just add a new hysteretic material with specific degradation rule

Hi. I think I found the reference for this hysteretic material. Check "Modeling of cyclic shear behavior in RC members" by Angelo D'Ambrisi and Filip Filippou (1999). I think this is where this uniaxialmaterial was taken
