It has a hip with spaced 1x sheathing, 2x4 rafters and 2x6 ceiling joists.
the vertical wall diaphragm is essetially a board and batten wall of 1x12 boards and milled batts. it's been a while but I seem to recall the raftes resting a 2x top plate that is then, somehow, attatched to the baords...
I have a 1920's cottage that is single wall construction (no stud framing). I am curious about how this system performs structurally, both axial and lateral, when transferring loads through this rather minimal 3/4" vertical diaphragm.
