While modelling plate girder railway & footover bridges I am having to connect multiple members from one girder to another. the problem I am having while analyzing is that I am getting Warnings showing members between same joints. How can I resolve this problem and model plate girder bridges more accurately. Also, if I release the moments in the bracings the results I am getting does not seem to be correct. This is another query I have? I have attached my model along with some gestures, I would also wan't the attached model to be fixed by some one.

In your model the warnings related to members being between the same joints may be ignored as you have defined offsets.
Your model had a number of zero or very small offset values which should be taken out. If you apply full MY MZ releases for the braces, you may get instability warnings at the brace intersections. So try using partial releases with 99% of the moment released. This would be practically the same as applying full moment releases.
A modified file is attached for your reference.
