Hard to see much in the picture of the joint or the rafter feet!

Hi Carlos,
We cannot see in the photo whether or not there is a dropped tie or crossbeam in place between the main posts but I rather suspect probably not and so if this is the case then the collar will be operating in tension since there is no other tension member preventing building spread.
This doesn't look too good to me.
Regards

Will, I see a lot of that roof type in Down East Maine. We also have common rafters.
Heath, put a cable in at the eve line and move on. The collar was doing nothing. That looks like a lot of roof for no tie member. I am wondering what the second plate is all about? The one with the fresh post under it. If that is what it is. Tim

good day
the second plate made two walls, an inter which was straping, the outer wall had vents from the 2nd floor about 3 ft up along both side of the corn barn. We think to dry the corn.
i learned alot from this barn like
every side board was a lap joint on top and bottom with a 45 dag bevel at the top so any water would shed away.
all the clap boards were over laped 4 to 6 in. insted of just butted agenst each other.
get the hewing thing down

Heath, how much structure was involved with the inner wall? I am wondering if its structure made a wall system stiff enough to withstand the thrust of the roof. Tim

Hey everyone,
So if there is no tie anywhere in the arrangement, then no matter where you put the collar it will be in tension?
If there was a tie below the plates or at the plates (don't know if this would make a difference with the collar arrangement) at what point does the collar move from compression to tension? Is it at the midpoint of the rafter?
At the gable ends of the pictured structure are the studs negating thrust? And will the spacing of the bents with the ridge add more load to the middle bent with the collar?
Sorry for all the questions. This seems like crucial stuff.
Thanks, mo

well this is what i got
there is a main top plat and a secondary top plat that holds up the iner wall.
now the secondary to plat has a tie beam mortis into that beam and then goes on the top of the main top plat like any english tie joint.
i wanted to make this building histoic as posible the only thing i did differnt was put the collar tie in.

The collar tie is an add on after???
Mortise and tennon? It would be imposible to put a collar tie in properly after the fact!!
How did you install the collar tie... more pictures would be helpful of the actual joints as much as possible.
