Log Beams
Log Beams
(OP)
I've never had to run the numbers on a round log beam before. Looking through all of my software that I use for beam calcs I don't think any of them has the ability to check a DF 11" Dia. Log. Any suggestions?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

When I compare this standard to the NDS (Ch. 6), the only real difference that I note is that the NDS has a condition treatment factor Cct whereas there is no mention of this in the 400-2012.

For a circular cross section the shear stress is 4V/3A, with a semi-circular cross section the other notes I have show a shear stress of approximately double this value, in reality though I think it may be higher due to the oddly shaped cross section and stress concentrations from the cope.
