When structural models are analyzed, they need to be analyzed using some Finite Element Method, and so they most probably may not be split up like an Architectural Model (the same can be argued for the mechanical and electrical models).
Using BIM 360 it is easy to do clash detections per floor level. Modern buildings are often split upper floor level architecturally, which makes the process relatively easy, but in a structural model, it is not that simple.
One may use section boxes to isolate parts of the model, but as one can’t align the section boxes with specific references (at best one can eyeball them into place), and if one errs on the side of caution, one will pick up clashes in separate views that would be duplicate.
I use worksets in the structural model for this reason. Groups are copied between levels. They attach to elements in the analytical model, and they assume the workset into which they are placed. This makes the worksets easy to manage. A 3D view is created for each level, so that one may easily see if there are elements in the workset that should not be there (a quick visual check).
Now when the structural model is linked into the BIM 360 Coordination container file, the published 3D views can easily be created per discipline and per workset. This is also true for the Architectural model if it has its worksets set upper level.
