Hi George, I try, as much as possible, to avoid some of the framing conditions in this plan, which is an example of the timber frame revivial style of the 70's and 80's.

1. I offset the top of the tie beams to the bottom of the floor joist and wall girts, which avoids over-crowded joinery in the wall posts and all the notching in the tie beams.

2. I avoid 20 foot spans on carrying beams.

3. I avoid unsupported roofs that load the plates with high thrust loads. Instead I utilize, alone or in combination, structural ridges, purlins or trusses to carry and resolve forces. Additionally the scheme you presented will magnify and concentrate the forces on the tie-post connection.

4. Keep the wall girts, which I view as joists, in plane with the joist and halflap the brace into the girt and run the brace into the plate.

5. Create overhang with rafter tails, buildings need shelter also.
