Replacing/exchanging beam
Okay, I mostly thought that 2 were more manageable than 1, I was planning to glue and screw them together, but surely one can be put up as well.
I was a bit off with the height, since current is 180 high, so a maximum of 225 would be good.
Would 165x225 work?

That absolutely works.nino said:
When I calculate now, I start from a load of 12 kN/m. Hopefully, it is overestimated, but I'm not sure. I think it's crucial for you to be certain about that. If you reduce the height to 225, you should probably increase to 215x225. However, I think it would be better to remain at the 270 height.
140x270 seems to be the standard dimension it ended up at around 1400 and a 165x270 at 3500 so there was a bit of a difference....
Do you think 140x270 is enough @justusandersson?

I would feel more comfortable if we had resolved the roof loads first, but with my assumption of 12 kN/m, a 140x270 results in a deflection of 1/500 of the span, which is considered acceptable given the circumstances.
One last? question @justusandersson
I will be cutting the existing beam at the 45x70 rule, and the remaining beam needs to be supported. For that, I have purchased a 70x165 solid wood.
Is it best to remove the studs and place it directly on the concrete and against the beam?
I will put it in place before the roof is propped up and the column is cut off.
The new glulam beam will also, of course, have a column, but I plan to have it measured to align with the new interior wall that will be built outside the existing wall (osb & studs in the picture) as it is a partition wall for the apartment. I plan to screw both columns together for extra support.
Does that sound like a sensible plan, or am I missing something?

I'm not entirely sure I'm following the geography... But a 70x165 can handle very large loads, especially if it is braced in the weak direction. Where will you place the support in relation to the old beam?

I apologize for the late reply. I have been a bit busy with other things. The best thing is that you can attach the post to the frame construction in some way. It is primarily the weak direction that benefits from bracing.
I plan to have it against the OSB board and standing on the concrete and against the beam, I'll do this before supporting and replacing the rest of the beam with glulam.
Then there will be one more, either the same size or maybe a little thicker, to support the glulam beam.
The two standing pillars I'll glue/screw together to one 140×165, or possibly it will become 165x165.
That should hold, right?

Absolutely.
Can the columns be placed directly on the concrete floor, or should there be plastic / cardboard or something similar in between? I think that what you place against the floor is likely to break when you tighten the beam.
