How to make Bilinear Slip Model

Post by ambitionpdf »

I would like to make a SDOF with Bilinear Slip hysteresis curve.

I used "uniaxialMaterial SelfCentering" command but it did not work well.
[ uniaxialMaterial SelfCentering $matTag $k1 $k2 $sigAct $beta <$epsSlip> <$epsBear> <rBear> (OpenSeesWiki)]

The rule I defined causes break points at the origin but I would like to make break points at the previous maximum displacement.
Can this command express that by changing <$epsSlip> <$epsBear> <rBear> values or do you have any other command you recommend?
