Need Old WWM Properties
(OP)
I am working on a project that the record plans show "316-28 WWM" for a 6" thick slab reinforcement. I assume it is probably a stainless steel wire mesh. Does anybody know how I could get the design info for it?
Thanks
Thanks

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I vote for 316 being a mislead for our modern mind, and not anything "particular" in a building of this age. The 316 has something to do with physical dimensions and properties, not a type of steel.

Also, American Steel and Wire Co. catalog of early 1900 has the 316-28 as a noted Wire Wire Fabric STYLE, as follows:
Let me see if I can dig up the STYLE details from my reference and post details here.

So total it all together and you get: "316-28" = #2 gauge longitudinal wires at 3" c/c, #8 gauge transverse wires at 16" c/c.
For reference: #2 gauge is 0.2625" dia. and #8 gauge is 0.1620" dia.

You are welcome.
Curious - for your project framing (located in NY I assume), was the WWR profiled/draped over the spans to act as both TOP and BTM one-way slab reinforcing?

Interesting equations in the same reference:
Assuming 8' spans, 3" average to depth of steel, with stone/gravel concrete, this equation gives you a 303 psf TOTAL load capacity.
