Switch off

I need to cut out a piece from a 100x230 beam just before the support.
I'm planning to place a 90x315 glulam beam underneath to replace the sawed-off piece, length 2600.

Is a 45x95 standing on each side enough as support? Double? Thicker?
The length is about 2600 and will be screwed into the existing framework and a pillar.

Red should be cut away.
Turquoise is the glulam beam.
The beam being cut out is nailed on the left and rests on a pillar 2600mm from there.

No one knows if 45x95 is enough as support for the beam?

At least I don't quite understand your picture in relation to your description; Why are you replacing it with a glulam beam that is much longer than the sawn-off piece, what is above what you are sawing off, are there plan and sectional drawings?

 

[nino]

There is a pillar on the floor below, the glulam beam can go from there to the wall, so the glulam beam should be in the ceiling on the floor below.
There is an attic above.
The red dot is where it is cut off, the red line on the second image is approximately where the beam will be in the ceiling, the square is a pillar.



I apologize if I have been unclear.

I also saw the wind came with it

Have I understood it correctly, according to my image below? If so, have you calculated the glulam beam? You need to know the load on the glulam beam so that you can then calculate what the forces in the supports will be. Once you have the force in the supports, you can check the beam's load-bearing capacity under compressive (normal) force with regard to buckling.

What is your c-spacing between the beams?

 

[nino]

Yes, you have understood correctly
I haven’t calculated, but I think that a 100x230 should be weaker than a 90x315?

The joists for the floors are on the other side and are approximately at cc 600, 3x9" approximately 75x230mm

 

[nino]

The supports will be screwed against the standing stud in the load-bearing wall and in the pillar.

It seems like the floor beams are laid between the joists. What is the distance between the sections? In other words, how long are the floor beams?

 

[nino]

Yes, they are probably around 3.5-4m I would guess.

45x95 is no problem. I have thought like this:

First and foremost, the wall extending out of the paper in section B-B does not seem to be load-bearing as the floor joists are not continuous over the beams beneath the wall. The imposed load between the compartments is therefore taken up by the floor joists, which appear to be fastened with joist hangers. The shear forces that arise are then handled in the connection. The loads are thus:

Non-load-bearing wall, dead weight: 0.2kN/m^2
Imposed load: 2kN/m^2 (The imposed load is not directly over the beams, but I have calculated conservatively). Imposed load from the attic floor and the upper floor.
Dead weight of glulam beam and the two beams from the upper floor and attic floor.

Height of stud that is screwed to the column: 2.5 m (even though it is less considering the thickness of the glulam beam and the beam).
