How to analysis different types of modeling slabs in ETABS

Analysis different types of modeling slabs in ETABS

Two different types (Thick, and Thin) of modeling slabs 16 cm (4 x 6) m2  have been analyzed in two cases.

Case (1): Supported on the beam’s edge
Case (2): non-supported on the beam edge

Your manager wanted you to answer these questions.

Q1-For Case (1): To what do you attribute the little variation in moment between the slabs?

Q2- For Case (2): If we ignore the self-weight of beam, how to explain the moment in the beam.

Q3- For Case (2): Despite the fact that the structural behavior for both slabs is different, why both slabs produce the same amount of the moment on the beam.
