I realize many factors come into play in the calculations, not just spacing and size but species as well. There are buildings that have been standing for centuries, long before a code enforcement officer insisted an engineer stamp your plans. If there is some sort of reference available, I would love to get my hands on it! July 22, 2019 at 7:54 am #22271 Brice CochranKeymaster There is not a chart that has the sizing for beams. I have been after the engineers for years to put out one out but have met with failure. There are a couple of timber of beam calculator, one is at http://www.forestryforum.com/members/donp/logbeamcalc.htm.
