4 1/4" x 16 1/4" glulam
(OP)
Hi,
I am to perform a site visit on a building with the above size glulams spaced 8' o.c. in San Diego to observe what the client says is a 4" sag and has been ponding. I have a framing plan with this size, dated 1962, but no specifications for these beams. Most glulams I have seen in the West are Doug Fir and sized 3 1/8"x and 5 1/8" x and up. I can't recall encountering this size before. I am wondering if this beam sizing might be familiar to someone and if you could guide me to additional engineering specs.
Thanks!

FYI, in one of the calculation example pages for glu-lam arches, I did notice a reference to 2200 psi glulams, so they were around at the time and available. Whether they were used in your case is up to you to find out though. 1600 psi would be conservative for bending.

When you really really appreciate, someone who has been really really helpful, like Mike has; that’s what the {“little pink stars” Like this post? Star it!} are for. You’ll find that right below Mike’s attachment box, in his second post. Click on it and see where it takes you, his effort deserves a LPS, from you.
