The "shelf" glu-lam in Wisconsin and Minnesota is 24F-V4 according to the
distributors that I have had experience with.

I am working on proposed revisions to the AITC 117-93 Design standard for
glued laminated timber. I am curious as to which combinations are being

What combinations do you specify?

Do you  know that there are 82 listed combinations in Table 1 (multiple
grade members used primarily for bending members). Bending strength levels
of 16F, 20F, 22F, 24F, 26F 28F and 30F. (24F means 2400 psi in bending).

Please make other suggestions that would improve this standard if you have
such ideas.
