end condition of glu lam 1

[AlpineEngineer]

I have a client who would like to miter the end of a glulam beam at a 45degree angle. They have 2 glulams coming together at the same elevation and the same bearing point and they want to avoid a hanger, so both beams would be mitered to fit together. Even with the miter I have my proper bearing area (2x6 walls help) but I am still concerned about the tension side of the beam. Any ideas about how I would go about analyzing this?

Is it the cost of the Hanger?

A Kerf connection would be hidden if that's what they want.

Cost is not the concern but they do want something hidden. I must admit I don't know what a kerf connection is, can you explain?? The load is 10kips. Thanks a bunch?

It really is a simple connection. All it involves is a single plate selded to a base plate, on the top for the beams, and the bottom for the columns, with thru bolts as required. A kerf is cut into the center of the end of the beam to receive the plate, the reason why it is called a kerf plate. For the two beam situation, there will be two "knife" or "kerf" plates on the top of the bearing plate, each along the centerline of the beam to be connected. If the connection to the column below is hidden, then you may be able to get away with two side tab plates below the beam bearing plate.

Ahh. I think I know what you are talking about. So I think what you call a kerf cut is the same as a plunge cut, is it not? I designed a log beam connection once like this. Great idea, thanks a bunch.
