this is a hollocore plank with prestressed strands in it. if we make any openings and provide steel angle to support the hanging edge the load will go to adjacet slab or adjacent tendon and will create torsion in the slab. just want to analyze the slab for such effects and see if the slab can withstand if we cut any tendon at such locations.
For a more "global" model , you could use an orthotropic panel , use Linear releases to model the slab interaction with each other and insert the holes as "opening" contours.
But it will not represent the slab literal geometry , only its stiffness. By that i mean that you not be able to precisely locate the holes according to slab geometry.
If you need a more "local" analysis , then I think you will need to go for a solid model ,or at least a more refined shell model(upper,lower and web plates as shell panels)
