If you have a script you think might be useful to others post it
here. Hopefully we will be able to get the most useful of these incorporated in the manuals.

Help!
I need to model a structural element that presents a multi-linear (as bi-linear or tri-linear...) behaviour: no hysteresis.
I need to couple this material with an histeretic law in order to obtain something similar to "flag shaped" histeresys. (for prestressed elements)
Has someone ideas or useful scripts?
Dear Silvia, can you help me?
Thank you in advance.

I think for trilinear behavior of material you can use two fiber sections with different bilinear material properties at same location in each section !

or use the parallel and series materials with the hysteretic material.
