How to model purlin

Hello everyone,

 

I would like to model a purling with a canteliver at one of its end. (see picture below). I have applied a gamma angle of 1,68° to the purling and an offset of 250 mm. The beam of which the purlin sits, has also an offset (if that is relevant in any way).

2023.02.06 - Question Autodesk panne.png

What should the release between the purling and its support be?

 

Moreover, I am gettin an instability type 3 at the end of one of the purlin (and if I delete the cantilever part, I get the same instability to the next purlin and so on)

 

How to get rid of this instability?

Can't seem to be able to attach the model.

Thanks a lot in advance,

Jules
