Hello,
I was looking at wood floor trusses and noticed something odd .. well at least to me.
Most floor trusses are built with the wood (2 x 3 or 2 x 4) on flat.
Why?
I know they are calculated to take the correct load but every roof truss I have ever used has been built with the wood "standing up".
I did a search and did see a few floor trusses built with the wood vertical but almost all were built with the wood flat.
Even the bearing area floor the mending plates is much less when built this way.
The only advantage I can see it to the builder who how has a much larger area to hit when putting down the plywood sheets ( did some carpentry "back when" and remember having to be careful the floor sheets landed the center of a floor joist and even that only gave you 3/4" for nailing).
I just thought it would be much stronger with wood in the vertical.
Thanks!
