Weight on upper floor in 1½ story house.
Hello,
It feels a bit late to ask this question, but I've built new walls on the upper floor, using double boards, meaning chipboard on the inside and plasterboard on the outside, which results in almost 100 kg per meter of wall. In total, there are 21 meters of wall, so 2100 kg spread across the upper floor. The old walls were just single plasterboard.
The intermediate joists are CC 60, 195x45 (from 1978). The total area upstairs is 65 sqm, and the maximum span is about 4m between the load-bearing walls below. Should I worry about having built too robust interior walls, do you think? Although, I have never heard of a house collapsing even when people drag pianos and hot tubs upstairs. I also don't experience any sagging or creaking.

No reason to worry.
It's even to the point that your spånskivor will make the walls function to some extent as very high beams, thereby distributing all loads more evenly across the bjäklag!

Thanks for the response, yes it feels like it's getting really stable, I have also glued the chipboard to all the studs (mostly metal studs). As you say, the walls that go across the joists should spread the loads. Also took the opportunity to drive in around 500 chipboard screws into the floor that was previously just nailed.
