Hello Sandeep, 

The materials are:

- Bolts: ASTM A325

- Beam and columns: ASTM A572

- Plates: ASTM A36

Yes I have large deformation effects ON. I have not looked at the Newton-Raphson residual, I will look and read the article!

Now I have wrote another post: Symmetry. I am trying to model the half portic, because the other side is impacting in the connection results that I am studying.


Thank you ver much!!
