Pinching behaviour

[brisidi offline]

I have two suggestions for future developments:

1) In my opinion, you could add a nonlinear element that accounts for a pinched force - deformation relationship. I would imagine it being something like the Pinching4 material that OpenSees has: http://peer.berkeley.edu/publications/peer_reports/reports_2003/0310.pdf

2) you could add some sort of graphical representation of development of plastic hinges, or damage/limit states.

Keep up the good work!

Thank you for your suggestions that we will definitely consider in future versions of SeismoStruct.
Note however that in SeismoStruct 2016 there is indeed graphical display of the damage and the reach of the limit states (both with colour and with textures of damaged material) in the deformed shape viewer. See the code-based checks and the performance criteria definition for further details.
