I have torn down the knee wall now the whole house is thumping

Could it be that the support legs are load-bearing? 120 posts now, what have you concluded?

That @degi is so tired of his newly renovated bathroom that he weakened the whole house so it will collapse on its own.

Have concluded that my legs are load-bearing and the thread has wandered off as usual

TS has probably understood his mistake now that it's been pointed out in about 100 posts. That a constructor needs to be hired and that it needs to be fixed seems obvious.

The question is if there are more tips on what TS can do right now to minimize the risks until the fix?

It has been done differently, with different principles in how loads are taken and how shear, compression/tension, and moment loads are transferred between construction elements. You can only understand this by finding out how it is done in each case and propose changes based on the specific situation. That is: that *your* house has held up when you've made changes to load-bearing parts that you don't understand how they work doesn't necessarily mean the same change is safe in TS's house. Don't assume. Gather the facts and analyze/calculate what needs to be done.

I THINK you are trying to state the obvious, didn't you read my last sentence in the post "That said, since you notice a difference, you should have someone knowledgeable in construction take a look at it."

I BELIEVE you are trying to open an already open door, did you not read my last sentence in the post "That said, since you feel a difference, you should have someone knowledgeable in construction take a look at it."

Your advice is correct. Your comparison that *your* house hasn't collapsed or (as far as you know...) been damaged after you made illegal changes to load-bearing structures is completely irrelevant or, at worst, dangerous: "aaa, but the guy on byggahus had made this change and it went fine...".

TS is gone, maybe the roof will collapse

TS doesn't have many reasons to respond anymore; the tips and opinions keep coming in... there's nothing more for them to say/explain. Now they need to decide how to fix the problem (which we probably can't practically solve for them at the moment).

One doesn't have to be a troll or weird to leave the threads sometimes. Some threads attract a lot of people, where many say the same things.

You come back when you have a new question or want to announce that you've solved the problem

Yes, but to confidently say that it will go to hell, and quickly, hardly helps at all. A bit of pragmatism can indeed be needed.

Hello!

We have bought a 50s wooden house that we have renovated.
One thing we have done is remove the knee walls to get "bigger rooms."

BUT

When you walk on the upper floor, it "thuds" a lot. (it didn’t do that before)
The closer you get to the removed knee wall, the more it thuds.
(It thuds even when my 4-year-old walks upstairs and we are sitting downstairs, so very sensitive)

The beams that go are very sturdy, I tried putting even more joists in between, but it didn’t work.
Now I’m starting to think that the knee walls had a function that pressed down the beam running along the house’s long side and thereby made it "stiff."

In the places where we still have the knee walls, the floor is perfect.
Anyone experienced the same?

My thought is to put up a couple of thick joists that "press down" this beam at the wall sides.

Or does anyone have a tip?
I would be very grateful for that.

Here is a picture when the floor is open, and the green line is where the knee wall was before.

Move to an apartment!

A safe trick is to curl up into a small ball and drink plenty of water

The original poster (OP) has probably realized their mistake now that it's been pointed out in about 100 posts. That an engineer needs to be hired and that it needs to be fixed seems obvious.

The question is whether there are more tips on what the OP can do right now to minimize the risks until the fix?

There's already so much nonsense here: Why not fill the house with foam sealant?

A bad advice, it would increase the pressure on the outer walls further

 

[boihus123]

It is oversized to withstand a worst-case scenario, like a snowstorm that occurs once every 50 years. So probably no risk of collapsing, and wood is very elastic, but if the roof does bend in

There is already so much nonsense here: Why not fill the house with foam?

Thinking of attaching a helium balloon to the roof to counteract gravity. To quiet the thumping? just pull the kid by the ear so they learn
