How to model a column with nonlinear behaviour??

[benzo]

Hi!!
I had read the SAP2000n examples which includes nonlinear behaviour, but only appear one-joint Nllink element. How can I model a two-joint Nllink element to study columns with local nonlinearities?? And also, the Plastic 1 Nlllink element needs a force-deformation relationship according to the Wen's model... how transform the moment-curvature curve into the Wen's elasto-plastic behaviour??

Thanks a lot!!!

Better late than never. In version 8 Draw menu there is a 2-joint link option. In version 7, if I recall correctly, just go to Draw menu, draw link by clicking on the 2 joints.

RE defining a force-deformation relationship, that is done by Defining hinge properties, then select frame elements and Assign hinges.
