Tech Note on notches and bolts hole in glulams.
Does not directly address you situation, but does kind of give some overall guidance.

It's a rafter to ridge beam in this case. The original design (stock plans) show lam-to-lam with Simpson hidden hardware. Since the TF has all the shop gear to make the notches, they want to skip the hidden (expensive) connectors and house the joist with GRKs to pin the rafter to the beam. This is a small residence, so the forces are fairly low. All I could come up with is separation of the laminations from bearing stress and possible "changing" of the grade of the top ply if a notch results in an imperfection closer to the edge than allowed (not sure which / if any lumber grades this would apply to). That last part might not even matter if they're balanced since the notch would be in the compression plies.

Just housing or also a mortise and tenon?

When we do this with timber, we simply reduce the section. Provided that the top and/or bottom of a glulam isn't notched any more or less than the inner plies, does anyone know of specific prohibitions against side notches for housing (likely to be 0.5 to 0.75" in a 5-1/8 wide member)?******* ****** ******* ******** ******* ******* ******* *** * Read list FAQ at: http://www.seaint.org/list_FAQ.asp * * This email was sent to you via Structural Engineers * Association of Southern California (SEAOSC) server.
