Visually Graded Lumber Design Values

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I'm studying the UBC 1997 for timber design, in particular, heavy timber, post/beam constructions.  The following items don't appear to be represented.
E.g. Table 23-IV-V-1 UBC 1997 shows "Values for joists and rafters". 
1)    Do these values also hold true for 2x_ on flat?
2)    Where do I find values for 3x_ to 12x_ visually graded lumber?
3)    Similarly; round pile values?
Does the UBC address the values that must be used for large sections design?  I am reviewing from 2x4 to 12x12 D.Fir-L (North) in a variety of sizes.
Thank you.
