Push-Over mixed structure

[StefanoPasquini6790]

Hi everyone,

I have to run a Push-Over Analysis in a mixed structure (precast pillars and beams, steel column and steel beams), like the one that you can see in the picture below:

Well, I have to create the non linear hinge for reinforced concrete and precast elements, for example with the following data:

How can I do it correctly??? When I run the analysis I have a message that the non linear hinge is wrongly defined.

I already have results for this model, obtained with another software, but I want to compare this results with Robot.

As you can see in the capacity curves, the Y direction have a perfect elasto-plastic behaviour, and this is a little bit strange.

Cheers
