How to define material nonlinearity on Sap2000 to use Pushover analysis

[Captains210]

Dear all
I am going to model a simple concrete frame on sap2000 then design it then use nonlinear static analysis (Pushover)
Therefore, my question is how can I define material nonlinearity of concrete, rebar and know when the material will crush or inter in nonlinear stage??!!

I can see nonlinear material data on sap2000

For concrete, should I modify (stress-strain data, F’c, Ultimate unconfined strain capacity, Final compression slope)?

For rebar, should I modify (strain at onset strain hardening, ultimate strain capacity, Final Slope)?
In addition, where will i find the values of (Fy, Fu, Fye, Fue)

Is there any document I can read?

Thanks…
