SAP2000: how to use NL-Link element for nonlinear analysis

[Sumatra]

Hi all,

I would like to know how to use NL-Link element (zero-length element) in SAP2000 in order to use in nonlinear analysis. Is it necessary to create 2 nodes in the same ordinates for this element?

I already read the manual book, but still my model was not showing the correct result.

Thanks
