bilinear model

[earthquakecivil]

Hi everyone,
I want to extract an elastic-perfectly plastic model (EPP) from a BoucWen model. Firstly, Are the following values for BoucWen model parameters suitable to convert BoucWen model to EPP model? Secondly, what values should be considered for "$Ao" and "$deltaA" parameters for that purpose? Thanks so much
$alpha=0.0, $beta=$gamma=0.5, n=25, $deltaNu=$deltaEta=0.0
