Shear spring material model

Post by m12s12sa » Fri Sep 12, 2014 12:03 am

Hi,
does anyone know which new unixial material are the authors refferring in this recent article (paragraph 8)?

http://onlinelibrary.wiley.com/doi/10.1 ... 6/abstract

I am particularly interested in this part "Before yielding, the yield force is updated at each integration time step using the instantaneous axial force and displacement ductility." Can anyone point me to a uniaxial material, possibly the one used in this article, that has this feature?
Thanks in advance,

F.L.

Hi,

The material was developed by modifying the existing opensees material, but it is not incorporated in the standard version of opensees yet.

You can still find the details in Section 6.2.

Thank you.
