Multi-Span Glulam Beam and Uplift
Multi-Span Glulam Beam and Uplift
(OP)
Here is a situation I have not had very often:

Notice the "FAIL" due to uplift at the support 3. What would be the best resolution? Cut the beam at support 2 or design the connection and post at 3 for the uplift?
I kind of like keeping the beam in one piece to maintain my lateral continuity.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

if your large span deflection is ok as a simple span, I'd be comfortable cutting it at support 2 and addressing your lateral connection.... minding the finishes, as noted above.
I'd be less concerned about roof.....

Sorry about the mix up on the notes. I initially choose a floor beam in the Forte software, I should have probably chosen Roof Beam instead. I reran it with the roof beam option and the numbers are exactly the same the only difference is the option to assign a pitch to the beam.
Forte is fairly decent for some things but I don't like that it doesn't allow one to specify enough details (ie. custom unbraced lengths etc...). I'll have to recheck this in Woodworks sizer for the bracing requirements.

You could also do a similar thing by leaving out the third support and kerfing the top of the beam to weaken it sufficiently.
