Question about Links elements (Sap2000)
(OP)
Hello,
I need to model a element to have different stiffness values in compresion and tension, but both together
I am trying to model a link in SAP 2000 (nonlinear analysis), but I need the links to have different stiffness values in compression and tensile, but both together.
I read anothre thread where someone said with a link with Gap and Hook, but to do this, i need to make 2 "links" in the same place? or how can be it done?
Another solution to do it is with "Multilinear Elastic or Plastic link" but i don't understand how to define it really.
Thanks in advance,
Atte.
Rodrigo Mercado.

The effective stifness option in the same tab is enabled for linear analysis only.So you will get the different behaviour in positive and negative moments.However what I described, is an example of a rotational spring,which is the simplest thing to model with a link element.If you want something more complex,you could provide some more detail to the community to answer you more properly.
