old southern pine density? 2

[SLTA]

Anybody know what the DL psf of southern pine from the 1920s was, or the density? I have worn out the phone and google... I have to be as accurate as possible on the weight for a remodel.

3/4" diagonal pine sheathing on a house from the 1920s, in Western North Carolina.

cheers!

I get what you are saying, but in the grand scheme of things, minor differences in the weight of sheathing should not be the deciding factor in what type of beam you should use - unless the only thing you are carrying IS sheathing or if you are designing to the gnat's ass - something that is a waste of time in wood construction, IMHO.

Excel, trust me that in this case, for this project, it matters.

That is why I was asking. I was curious why it mattered so much.

Excel, I was thinking the same thing. In new design, you can just throw 10psf weight of materials at the design and run with it. But maybe it is a historic building or renovation and he can just barely make it pass code. But then someone better tell them to never exceed 50psf LL (or whatever LL is)
