Concrete stud wall, why isn't it a thing?

[Sman1]

Hello,

I'm wondering why there isn't a concrete stud wall? (Like a regular load-bearing wooden wall but cast in concrete)
You would save enormous amounts of material, and a concrete stud wall should be able to handle the loads from a small one-two story house.

Difficult to cast? Would it buckle under lateral loads, although a wall primarily bears top loads?

What material are you saving?

What material are you saving?

Concrete I thought, since you're using concrete studs instead of a massive prefab concrete wall. But I don't know, maybe it feels a bit unnecessary since concrete is cheap.

Well, you might want to think it over again.

It is not really a problem, except that it's a bit complicated. You have to build formwork on site, etc. The concrete truck has to go twice instead of once. Installations can't be supplemented without cutting tracks in the wall. However, you can have installation layers on the outside...

Looking at the economic aspect, there isn't anyone delivering standard-packaged houses who thinks it's a good idea. However, there are townhouses built in this way, with concrete slabs and load-bearing walls. I don't know, but I guess the elements were prefabricated. Maybe someone else knows, but it's probably possible to achieve cost-effectiveness if you make many modules, like townhouses. The acquaintance I have who lives in such a townhouse, the house was built in the 70s or 80s. I don't know if it's still done, maybe it became too expensive (?).

You haven't encountered a concrete frame structure, have you? That's what I think ts is suggesting? I can think of dozens of disadvantages but no advantages, sorry.

You haven't exactly encountered a concrete frame structure, have you? That's probably what the OP is suggesting? I can think of dozens of disadvantages but no advantages, sorry.

mm, didn't read well enough. No, why would one do that?

I was thinking cast-in-place wall...

The only "regulation" that works better in concrete are the so-called hollow core slabs for intermediate floors.
They have the most torsionally rigid shape; square on the outside and round on the inside.

Concrete construction with prestressed cables as reinforcement; brilliant.

What is often done is to let the floors stand on concrete columns and then build walls between the columns (and wherever you want a wall) with steel studs/drywall (possibly plus OSB or plywood).
This works well for commercial spaces, such as shops, offices, etc.
