Steel Floor Plate

Steel Floor Plate

Steel Floor Plate

(OP)
I am looking for some resources for specifying or designing steel floor plate.  I have an industrial application that calls for steel checker plate for the floor to match existing adjacent construction.  I can provide supports as needed to limit spans.  I need a 60 psf live load.

RE: Steel Floor Plate

Look up roarks for plate deflection formulii, deflection will always govern.

RE: Steel Floor Plate

The NAAMM Metal Stairs Manual is a good source of info on floor plate.  1/4" will span about 4' with your load but the deflection will be over an inch.  Since deflection governs, what is your criteria?  

RE: Steel Floor Plate

(OP)
Existing construction is 12 ga checker plate.
It has supports in both directions 2 ft to 3 ft o.c.
The existing structure was erected without engineering.
I now am trying to match or get as close as I can.  

RE: Steel Floor Plate

Note that checker plate, contrary to popular belief, is slippery stuff, especially when wet.  It's common to coat it with a grit type coating to provide traction and try and avoid lawsuits!

RE: Steel Floor Plate

The 13th Edition of AISC has some useful floor plate properties and span charts.

As mentioned earlier, Roark has some good stuff in it as well.
