Surface Load Placement and Composite Deck

[Anonymous]

I am learning Robot and cannot figure out how to properly assign surface loads without corrupting the floor slab.  I tried having one composite slab and then assigning the loads to cladding, but that would delete most of the floor except for a miniscule arbitrary area.  I also tried creating a composite slab for each area, but then the composite beam module wouldn't run because there was more than one slab assigned to certain beams.  The framing does not align exactly with the different load areas (a beam may have a hallway over part of it).  How are you supposed to properly input surface loads?

Also, is there a way to "design all" for beams that do not have a composite deck (i.e. steel roof deck)?

Thank you for the link!  I was asking more about how to place complicated loading though.  For the example in the presentation, the surface loads were constant across each floor.  For my project, the loads vary because of mechanical rooms, hallways, typical floor areas, etc...  How are you supposed to assign multiple loads to select areas on each floor?
