Hello I am first time here and I just started my adventure with meshing and FEA. I have problem with connection parts when I use midsurface (there is a gap between plates). 

When steel beams are intersecting each other should I just extend one of them to the other one to fill the gap?

But I have no idea what to do when they stick together side by side for example by bolts or welding. The only idea I have is to join some nodes after meshing using RBE element but I am not sure.

Help me. Thank you! Example photos attached

    Sure, you're right

    the way you used rbe2 is similar to the way you welded or bolted parts in fact

    Just refer where they welded them (position, length of weld)
