I found a reference here (https://www.fpl.fs.fed.us/documnts/fplgtr/fplgtr190/chapter_12.pdf https://www.fpl.fs.fed.us/documnts/fplgtr/fplgtr190/chapter_...) that discusses the mechanical properties of some of these fabricated structural wood products. Everything seems to be in comparison to just plain hardwood, but nothing seems to point to that it meets or exceeds the strength of hardwood. I am not convinced that any amount of glue, plastics, and pressing together other hardwoods (presumably, young woods as well) will stand up against good old fashioned old wood timber, which I simply don't think we have enough of to start building tall buildings with. If that's the case I'd rather be on the top floor of a steel building.
- mikeash 8y agoThey’re only going to design the building to be strong enough to withstand the loads it needs to bear, plus a standard safety factor. If they use a stronger material, they’ll use less of it so that the resulting strength is the same. I can understand being skeptical of decay, fire resistance, sound deafening, or other factors like that, but being worried about the strength makes no sense.
