RE: Engineered lumber bolt bearing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The direction of the grain in LVL is all in longitudinal direction.  I think
you could assume the same for PSL. The capacity is based on the yield limit
equations which are based on the density and modulus of elasticity of the
wood.  If the wood is more dense the modulus is higher you get a higher
strength.  The direction of the grain is the same.

Are LVL and PSL lumber considered perpendicular to grain for bolt bearing
values?  Seems like you would get a higher value for an engineered product in
an epoxy (?) matrix as opposed to natural wood grain.


Is there an increased capacity available?


Mr. Showalter, are you out there?
