2009 IBC Table 721.6.2(4)
(OP)
For a floor assembly, under the subfloor column, what is constituted as a T&G "softwood"?
Are they taking T&G planks made from a softwood, which seems ridiculous in today's construction, or T&G plywood, which seems more reasonable?
Sometimes I wish they would not try to confuse the issue and just speak plain English.

I think that this section of the IBC is using "softwood" to refer to conifers like Douglas Fir, Hemlock,Pine etc. that generally don't loose their needles in the winter and "hardwood" as deciduous trees like oak, maple, etc. that do loose their leaves in the winter.
I hope that this helps.

Somehow, I just have a hard time wrapping my mind around trhe idea of DF being soft. After 100 years, you cannot drive a nail into it, especially with the nails manufactured today. 99, maybe. :)
