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 table.
Durbar is the leading brand of structural steel floor plate made in the uk for over 50 years only by tata steel.
The pattern of diamond studs on genuine durbar is on average 23 deeper than generic floor plates with 10 more studs providing outstanding slip resistance.
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.
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.
Flat plates stress deflection equations and calculators.
For a rectangular section f is equal to 1 5.
At other points there are biaxial stresses in the plane of the plate.
Many of the stress and deflection equations and calculators referenced from.
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 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.
For class 1 sections.
2 145 in the 9th edition asd manual indicates that the loads are based on an extreme fiber stress of 16 ksi and simple span bending.
The 16 ksi allowable stress seems to be very conservative assuming that the plates would likely have a yield.
The ratio of mp to my is called as the shape factor f for the section.
