I see what you mean about the 4-way joint at center posts. There's actually no reason that it needs to be there. I plan on running the floor joists in the gable-to-gable direction and I can offset them from the center post. I wanted to use the half-round logs that were used for the ground floor in the original biulding. As such, they would need to be set into notchs in the tie beams.
The picture below shows some of the joists on the right.
I also posted a page with pictures of the original barn before dismantling, during dismantling and after dismantling.
