Steel Beam to Concrete Slab Connection
1- Separate this floor slab into two and remove the concrete footbridge. (Are there any shortcuts to doing that? I only can think of deleting both floors and redrawing them.. but it is a huge building so if there is a quick way to split that would be helpful..) 2- Add the steel beams (that should be straightforward)
