Forces in a slab acting like a stiff element

[eiriknor]

I have a horisontal floor bulid up by hollow core elements. This floor shall transfer the horizontal forces caused by wind and earthquake from the floor and to the stabilizing walls. But to desing the proper amount of reinforcement connecting the hollow core elements I need to know the moment an shear forces in the floor as if it was a beam. I this possible in Robot, I have looked at the results map and the Nxy and Nyy, but this isn`t giving me any results that I know how to use. I made a simple test-file (attached) and some pictures to show what I mean.

Mind that you can get the values of in plane bending  for panels directly.
