Diamond Plate Diaphragm
Diamond Plate Diaphragm
(OP)
Has anyone ever come across any information on the use of steel raised-pattern floor plates as diaphragms? I am considering using 1/4" floor plate welded to mezzanine framing as a diaphragm for mezzanine seismic resistance.
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've made this rationalization for using steel grating. I specified that it had to be welded to the support structure instead of clipped. All has been good so far.

The only part I am not a big fan of is all of the overhead welding of continuous sheets.

As far as AISI and SDI values, I do not have it in front of me but I have only seen values for closely spaced support members (16" or 24") While I can not span much farther than that with the metal plate, my support spacing will exceed these values. I agree with you that that data and methodology may be the most directly applicable though.
Thanks All.
