There are methods out there to field replace dry-rotted portions of glbs and strong backs them with a system of tie rods that are bolted to each side of the beam. . I had it done on a building in SoCal about 4 years ago. Seemed pretty simple..

Subject: QUESTION REGARDING GLB REINFORCING?
I am working on a restaurant job that has an arched glulam roof beam with signficant dryrot damage at the last 6 feet or so. Tyring to look at all options I was thinking about reinforcing it with 20'-0" long steel channels on each side and then welding the channels to a TS column. The bolted connection between the channels and the glb would obviously have to develop a moment to carry the roof loads. However, I remember in a wood course way back that although it is possible, a moment splice in a beam is not recommended and very difficult to correctly analyze. Any thoughts or recommendations or warnings. (see attached pdf) If the pdf is not postable I can email directly.
Thanks in advance,
Mike
