Hello,
I have a "sportstuga" built in '71 (snow zone 2.0-2.5) that has been renovated in stages. Among other things, the wall I marked in the section sketch has been partially removed, an opening of about 3.8m. The visible beam/plate 100x100 remaining in the opening clearly sags in the middle.
As I understand it, truss rafters are often self-supporting, but if not a load-bearing wall, it might be relieving? Something complicating the reason for the "sagging" is that a load-carrying beam previously broke due to earlier moisture problems (rectified for sure 15 years ago).
It is hard to see exactly what the previous owners have done, but what I think speaks for/against is:
Speaks for being load-bearing/relieving:
• Drawn in the section sketch
• opposite direction to the rafters
• partially part of the outer wall, many windows on the former veranda
• the beam "sags"
Speaks against being load-bearing/relieving:
• truss rafters
• thin timber?
• rather caused by a break in the load-carrying beam
So the question is what the solution should be, to relieve with a glulam beam or the like, alternatively prop up, lift and reinforce the side braces?
