Self Centering with Stiffness degradation

[Sudan]

Hello Frank,

How can I model self centering model with stiffness degradation. As far as I know from command manual, I can model Self Centering system but it has fixed elastic post inelastic stiffness. I need to model self centering system having stiffness degradation. How can we model it in OpenSees?

Regards
Sudan

If you are using the SelfCEntering material you cannot .. you will have to go in and create a new material by modifying the original.
