The ratio of mp to my is called as the shape factor f for the section.
Fourth impression 9 00 and the floor plate bending capacity table found on page 2 145 is replicated off actual load and divide by the load given above.

For a wide flange section f is equal to 1 1.
If you ll review the floor plate capacity table on page 2 145 of the asic 9th manual asd you ll see that there is a deflection line of 1 100 of the span shown.
Varma in figure 4 my is the moment corresponding to first yield and mp is the plastic moment capacity of the cross section.

Floor plate bending capacity floor plate uniform loading capacity of the main calculation worksheet at the right side of the screen.
From the table derived in section 2 of this document the maximum allowable load acting at the mid span on a plate limited by bending resistance is 58.
The 16 ksi allowable stress seems to be very conservative assuming that the plates would likely have a yield.
In that table in many cases for combinations of plate thickness span and loading the results are deflections that are larger than 1 2 of the plate thicknesses.
For class 1 sections.
Durbar is the leading brand of structural steel floor plate made in the uk for over 50 years only by tata steel.
At other points there are biaxial stresses in the plane of the plate.

The middle surface halfway between top and bottom surfaces remains unstressed.
The follow web pages contain engineering design calculators that will determine the amount of deflection and stress a flat plate of known thickness will deflect under the specified load and distribution.
