CSA A23.3 Interface Shear Transfer - can we interpolate?
(OP)
Re: CSA A23.3 Clause 11.5.3 Interface shear transfer: Do you think that it might be acceptable to linearly interpolate the values of “c” and “μ” for surface roughness amplitude between 0 mm (c=0.25, μ = 0.60) and 5 mm (c=0.50, μ = 1.00)?
For example, if we had roughness of say 2.5 mm full amplitude, might we take c = 0.375 and μ = 0.80 ?

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.

It needs to be measurable, achievable, and reliable. Existing surfaces need to be tight and free of dusting or lose material. Everything I've seen that would have qualified as a 3mm or so existing had lose and or friable surface material.
Anything less than 5mm (I'm seen 3mm specified many times) is simply not realistic. I often specify +/- 8mm and design to 5mm. But then again, I think history has shown me to be a fairly cautious engineer...

I will try to put my hands on the Quebec Ministry of Transport roughness checking procedure. They are the only authority I know to have published a formal test procedure.
