Is dovetail joinery for greenwood timber frame a good joinery style? Any difference joineries sugges

Logs are going to be like 8 x 8. I suppose dovetail would work for all joinery and I believe the simplest. Any other joinery better? Would a male / female connector joinery with pegs be superior?

The picture is a birdseyeview of a 20' x 24' foundation (stone pillars) and the woodenbeams which will be joined together with joinery. The beams will be acting as a sill plate for the joists.

You can, but most timber frames use mortise and tenon joinery. They do use dovetails on the joists, but your plan does not show them.

I also noticed you have a lot of joinery in your plan. At only 24 feet, why not just get 24 ft beams, do your corners and then mortise in your center carting beam. You would reduce your jointers work by 2/3 and have a much more ridged structure? With a frame that is kind of required.

I've tried a bit of dovetail joinery on greenwood and it failed.  The green wood just wasn't strong enough to hold when stress was applied.  I'm guessing if I let it sit for a year and then stressed it, it would've been fine.

Beau and the PTJ crew built this grape arbor and he demonstrated using a dovetail joint in this video:


But I'm not totally sure if the timber is greenwood or cured.
