(OP)
At what interval would clips be required for grating attachment to provide adequate continuous bracing of the compression flange of the support beam?

What is your span length? What is the size of the main beams?

How close are you from making the beams work if you consider the compression flage unsupported?

I personally think that if the metal grating is rigid enough, welded continuously to the main beam compression flange and the main beam spacing is not so large, then I would conside the main beams to be braced. Lateral bracing will only require to handle 2% of the total compression force in the member.

Thanks for your post, though I don't know how a quantitative check of the grating would help me determine the allowable bending stress of the beam, which is currently the limiting factor as it is not braced against lateral displacement. (I know the meaning of the word "quantitative", but don't know what you mean in your application. You mean load it to failure? If so, not practical). I'm sure your approach has merit - please clarify.

You may also try looking into research papers to see if anyone has tested this arrangement for its performance as a system. What I'm getting at is I don't think it's adequate to say it's ok without checking anything with numbers, especially with so many opinions to the contrary.

If the grating has a load capacity of 140 psf on a given span without much deflection, I think that should give some clue about its rigidity, should it not?

grating is removed, the clips are not replaced. The grating is simply laid on top of the beams. Bye-bye lateral support.
I can see grating welded to the top flange as providing bracing to the beam, provided that the grating is similarly attached to something rigid enough to provide lateral support, like a foundation wall. Two parallel beams cannot provide bracing to each other in this manner.

Is there something in the literature, such as a research report, to back that up?
