RE: Engineered lumber bolt bearing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Yes, when developing design values for SCL (general term for products like LVL & PSL), bolt dowel bearing perpendicular to grain is considered.  I'd suggest you review the appropriate ICC ES ESR Report and/or design literature for the company in question.

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?
