Dear STKO Team:

Thank you for your reply.

I used Takeda hysteresis model in ETABS. There is no Takeda model in OpenSees, so I use Modified Ibarra-Medina-Krawinkler Deterioration Model.

1. So Takeda hysteresis model doesn't consider cyclic deterioration parameter, right?

Best Regards

From your ETABS hinge plot, it looks like there is no cyclic deterioration
