Another question regarding a load-bearing wall, I'm in the process of taking down the wall between the kitchen and living room. I and several others assessed the wall as non-load-bearing. The house is a Gullringshus from 1966. The wall is longitudinal with the roof ridge. The distance between the outer walls is 7.4m. The only walls I can find marked as load-bearing in the drawings are the basement walls.

I have truss roofs, and the studs in the wall were, in my assessment, very weak, 50x35mm. Also, the distance between the studs was over 100 cm in one place, none of the studs were centered with the floor joist. The wall was between 2 door openings and ends with an opening of 4 m.

During demolition, there was pressure on the last stud closest to the outer wall, but when sawing, the stud cracked easily, and the roof dropped about 10 mm... the roof is now supported back to the height before demolition. So my question is, did the wall have a load-bearing function, or is it normal for the roof to sink somewhat over time?

The only thing I can contribute is that if you removed the wall and the ceiling sank, you've removed a load-bearing wall. Something normally settling due to age doesn't happen by chance at the same time as you demolish the wall.

The wall you have torn down is marked on the sectional drawing (the one with the house cross-section seen from the gable) and usually only load-bearing walls are. Now, the relevant wall is not entirely aligned with the heart wall/wall in the basement, but it is still something that makes one a little concerned.

According to the drawing, you have demolished a load-bearing wall!

The house is a Gullringshus from 1966. The wall runs parallel with the roof ridge. Distance between exterior walls is 7.4m. The only walls I can find marked as load-bearing in the drawings are the basement walls.

I have truss rafters, and the studs in the wall were, in my assessment, very weak, 50x35mm. The distance between the studs was over 100 cm in one place, none of the studs were centered with floor joists. The wall was between 2 door openings and ends with an opening of 4 m.

During demolition, pressure had been applied to the last stud closest to the exterior wall, but when sawing, the stud was easily snapped, and the roof dropped about 10 mm.. the roof is now propped up to the height before demolition. So my question is, did the wall have a load-bearing function, or is it normal for the roof to sink somewhat over time?
I live in a similar house (LB), and several neighbors have removed the corresponding wall. That the roof sags isn't so strange when the span becomes longer. It doesn't necessarily mean the wall is load-bearing.

So you mean that the sectional drawing shows a non-load-bearing wall in TS's case?

I'm really not saying anything at all. More than that it's quite possible that it actually isn't!

That said, things may have changed since the houses were built. For example, opening up for windows or similar and thus altered the load-bearing capacity in different ways.

I interpret the drawing as if you have demolished this wall:
Blueprint of a house roof section with a red circle indicating a wall that may be removed, potentially affecting roof truss support.

And it is presumably needed to support the roof trusses somewhere in the middle of the house.

Besides the wall being drawn on the section drawing, I note that the roof trusses are asymmetrical. Which would be a bit strange if they were supposed to be self-supporting over the entire span between the outer walls.

The outer wall is 1.20m further out in the bedroom section than it is in the living room.

Earlier you wrote, “I live in a similar house (LB) and there are several neighbors who have removed the corresponding wall. It's not so strange if the roof comes down since the span becomes longer. It doesn't necessarily mean that the wall is load-bearing.”

And now you're saying nothing at all?
According to the drawings, it strongly appears to be load-bearing as it has been included in a sectional drawing..
But what do I know, maybe you have enough knowledge since your neighbors have removed their walls in their houses!

I would also say that the fact that it is included in the drawing and that the truss is asymmetrical to compensate for the longer span on one side suggests that it is load-bearing.

Yes, but according to the same drawing, no exterior wall is needed either because the roof is flying in the air!

You, however, seem to be an expert who has an incredibly clear picture of how it is thanks to a post on a forum. Maybe you should become a structural engineer?

Yes, still it's the bedroom section that is the "weak" side.

You're circling the external wall!

Maybe you shouldn't write on these matters since you can't interpret drawings, it's a recommendation for your own sake so that you don't embarrass yourself further!
