Glulam Post Base Moment Connection

[XR250]

There have been several threads about this but I would like to get some additional information. I have a free-standing carport that was designed using flagpoled tube steel columns. Now the Architect wants to switch to glulam columns and beams. The service base moment is 4.5 ft-k. Seems like my options are a shoe, a knife plate or burying the treated column in concrete. I prefer to bury it just from an ease of construction standpoint but, of course, there are debates about rot. My problem with a shoe is getting the column to fit it tightly. Potential knife plate issues seem to be getting the contractor to drill a proper hole in the wood for the bolts. I am worried about looseness that might cause the carport to shake. Do glulam suppliers have bases that can be used for this with pre-drilled columns?

What has been y'all's experience with this issue?

Thanks!

Nice, thanks so much. Apparently, I now exist in some kind of bubble where industry developments aren't reaching me...

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.

True, but it's better than nothing.

Massively better than nothing in my opinion. If they can do it, I can too.
