Wood grade/Species

[JStructsteel]

Aoyone here local to Ohio and have an idea what wood species would have been used? Central ohio, near Lima (I know thats pretty specific).
Its dimensional lumber. Im not good at identifying wood by looks, unless hardwoods.

Not local to Ohio, but looks like pine to me. A positive identification usually requires a really good magnifying glass or handheld microscope. https://extension.msstate.edu/sites/default/files/publications/publications/p2606.pdf

Thanks. Based on that picture, could you say its #1 pine or are those knots large enough to deter #1 grade?

Its probably a moot point. I have some joists that are 15'-11" w/ heavy DL due to fire protection. I know I will never get there due to deflection.

Number 1 is questionable, but not out of the question. The grain on some of them looks a bit...loose. I'm assuming that wasn't built yesterday - I'd use pre-2013 No.2 values unless some of them have big ol' knots right on the tension face.

Looks like lath and plaster were on the walls, so likely built long ago.

Yeah, but look at those solid brick walls. Just screams modern construction.
