How and with what should one offset

[Färdigrenoverad]

Need to create an opening 180*210 for patio doors in a load-bearing exterior wall. This is on the ground floor, so there is an upper floor. The floor joists for the upper floor rest on the outer wall, and the roof weight is also transferred down to this exterior wall.

Should one choose a concrete beam, glulam beam, or steel beam? Does the beam need to be as wide as the lightweight concrete blocks? Can a horizontal stud that is as wide as the lightweight concrete blocks be placed between the beam and the lightweight concrete blocks instead of the beam having to be wide? Is there any point in having vertical glulam beams besides the support on the wall (X)? How much must the support be, at a minimum, on each side?

This is how it should be.

Have you had any dialogue that we can't see because there's a lot of information missing to be able to determine dimensions just like that?

There are calculation templates for this kind of thing.
Calculated on two planes heavy roof and floor with house width 10m and load-bearing heart wall and zone 2.5.

Well aware of this, but the information provided is not enough to determine a dimension. Even if guessed assumptions would suffice, it is wrong to give such advice without the true prevailing conditions.

You have room for double the width in the wall if you really want to take it up a notch.

You have room for double width in the wall if you want to go all out.

Thanks for the reply. I like to over-dimension, if you double, should you nail/screw/glue together the studs and beams so they become a bond?

But that's not what this is about, you're giving advice on something without knowing any conditions. It's just a small opening in the outer wall and it works guaranteed, but as a designer, you should be aware of the whole picture.

But that's not what this is about, you're giving advice on something without knowing any prerequisites. It's just a small opening in the outer wall and it will definitely work, but as a designer, you should have a grasp of the whole context.

Not sure if you've noticed... This is a forum.

No "guarantees" are given here and no one expects "just the truth" and actual "designers."

You get the answers you deserve and take them for what they are...

I'm actually surprised a thread has never appeared on the legal side: "I followed advice and feel deceived."

So critical thinking and a bit of self-preservation are needed here.

Now he referred to design templates and I checked this one and according to it, his suggestion is a little more than sufficient for me.

He referred to calculation templates and I looked at it, according to which his proposal is a little more than sufficient for me.

Interventions in the facade and load-bearing structure are usually associated with building permits. I guess they will be super impressed by screenshots of the calculations from some random guy on the internet.

Have been in contact with the municipality, slightly different rules outside of the detailed development plan area.

Planning to create an opening 180*210 for patio doors in a load-bearing exterior wall. It’s the ground floor, so there is an upper floor.
The floor structure for the upper floor rests on the exterior wall, and the roof weight is also transferred onto this exterior wall.
Should one choose a concrete beam, glulam beam, or steel beam? Does the beam need to be as wide as the concrete blocks? Is it possible to place a horizontal stud as wide as the concrete blocks between the beam and the concrete blocks instead of the beam needing to be wide? Is there any benefit with vertical glulam beams besides the setup on the wall (X)? How much support must there be at least on each side?

Hello,
I just have to point out that you don't insert wooden beams into a masonry construction.
So it remains casting or steel for your part, I don't know any calculations but it should be looked at by a structural engineer whether the municipality is involved or not.

Kind regards, Janne

This is how it should be.

Completely crazy according to all construction rules! You don't install wooden beams and posts for supporting structures in a masonry.

You can calculate the weight of the wall above as an evenly distributed load. Then add what the rest of the second floor and the roof contribute. There are simple tables available from those who sell beams. Or, of course, formulas. Personally, I would choose a wide HEA-beam or similar. In steel.
