Restoring the yurt on our property. The foundation has settled on one side (the other is concrete). Removed the tilted chimney and found this. Looking for suggestions on how to fix this. Thanks!

Restoring an old yurt. Foundation is half concrete and half wood, which has settled. Removed the leaning chimney and found this mess. Looking for suggestions on causes and fixes. Thanks!

Looks more like a DIY permanent frame yurt, with moderately-sized metal brackets holding the crown ring together. As long as you don't put much load on the roof, you could probably jack the center up until it's even then install unbent hardware. But if things bent like that in the first place, the metal bits/connections may have been unsized in the first place...

Do you think the silver ring was installed to be load bearing or otherwise structural, or is it just to hold the chimney pipes? We are thinking that the problem was caused primarily by the foundation settling but there was also a chimney fire that burned the roof joists and was not properly repaired that may have contributed to the problem as well

Hmm hard to tell completely, but it looks structural to me just from what I understand of yurts. The compression ring up to holds all the weight coming in from the tension (outside cable or structure). It is pretty important.

Curious if there was any other venting in this roof? Looks like there were moisture issues, which is why I ask.

No venting and definitely moisture issues. Still working on stopping the rain from coming in. Roof will most likely be fully recovered-decked.

Seeing as you have a hard roof, definitely consider venting it. It is a common issue with fabric yurts that people over-insulate and then found mold/moisture as a problem. Of course, popping a vent in a fabric roof is not very practical. Your set up though, should allow this. I would also suggest exposing rafters as much as possible (it looks like you have).

If venting is absolutely out of the question, then you will need some whole-house dehumidifier at least. This forum is full of moisture threads.
 
Thanks! Good to know. I'm sure we can vent the roof. Thinking about a metal roof.

Well the beginning of that thread is page 1, this is page 2. See page number at the bottom right of the screen above the quick reply box.

There is no spiraling or torquing in that picture that I can see.

Thanks. Why do you think the ring has slipped? Do the cables stretch? We think our yurt is over 50 years old.

I am guessing as the structure moves in the wind or for whatever reason, the rafters slowly wrench their way upwards. Kind of like wiggling a cork out of a bottle. On most manufactured yurts you see today, the rafters are attached to the center ring somehow. Some bolt them in with brackets, or like my Pacific Yurt, they are pinned into the ring. That is to say there is a hole in the ring that accepts a pin that is protruding from the end of the rafter.

I am not exactly sure how you would get them back down safely. I would think that somehow you would have to jack the center ring up with a post and floor jack? I am no engineer or carpenter though so don't take my word for it.

Thanks! We were looking at jacking the lower ones up and the ring with them. There is an interior wall (bathroom) that appears to be holding roof joists up, in what we assumed is the original position, but we don't know for sure when anything was dinner so the bath walk could have been added after the shift.
