Hi,
Just stepping in and out with a question. These last few posts in here are great. Will's post attempt to answer the "Why" of the situation. I find this part the most interesting.
Will, when you say the "tie fell away". What do you hypothesize caused this. If I am understanding correctly, the canted posts are supposed to negate the thrust, which would in turn negate the tension in the "tie". Is this thinking right? If it is right why would the tie fall away? That midspan post I expect contributes to this equation in some way.
In the second picture, you can see the tie is away from the housing and it appears that the tie has dropped from the force of the strut and canted post. I can see this making the post bend above the tie (extremely it looks)from the rafters falling with. So does that mean the ridge is dropping in the middle bays? Does the ridge have a concave sweep to it when looking at the barn from outside? Would looking at the plumb cuts of the rafter at ridge, give an indication of how much this ridge has fallen?
Sorry to butt into this great topic. Im a firm believer in answering Why before What to do now.
Really appreciate everyone's knowledge around here.
