WHAT IS THE ESSENCE OF GENERATING MESH ON SLAB BEFORE ANALYSIS

If i model my project and add slab,what will be the difference if i dont generate plate mesh, after adding slab i add load and run analysis without generating mesh.

  • I have designed slab using parametric model (By Generating Plate mesh) and compare results by applying 1)Plate pressure load 2) Floor Load. And I got the different results in both the case. Please help me to know, which approach is the realistic approach to design slab ?

    1) As,  I am getting max stresses in the middle portion of the slab under plate pressure loading condition and max stresses in the     middle edge beam under floor loading condition.

    P.S - While Applying Plate Pressure and Floor Pressure (Keeping load value and all other parameters same for comparison)

    Case 1 - Design Beam and Slab by applying Plate pressure load uniformly distributed over whole slab (In this case I am getting max stresses at the center of the plate)

    Case 2 - Design Beam and Slab by applying load of  Floor pressure (In this case I am getting max stresses at the middle beam).

    Case - 1  Beam Design with Plate Pressure Loading

    Case - 1  Plate Design with Plate Pressure Loading

    Case 2 - Beam Design with Floor Pressure Loading

    Case 2 - Plate Design with Floor Pressure Loading
