Sent up a 7 m long glulam beam (630x115) to the attic a few weeks ago. The two pillars stand on masonry basement walls, just like in your case. Forget about steel; if your small beam (220x45?) has held up until now, there should not be any problem putting up a somewhat larger and longer glulam beam
But let an engineer calculate it.
Damn, high beam:wow:.. I think the reason why my small crappy beam doesn't sag at all is that all the trusses are self-supporting. I will check this with the engineer.
Belt and suspenders?
It's a little over 7 meters between the supports and this was what the designer wanted, so I didn't argue The first thought was an HEA 220 steel beam, but that would have been costly since I couldn't do it myself. Despite the size, it only took 15-20 minutes to get it in place (the first part with a crane truck).
No extra posts. The intermediate floor is concrete and the basement walls consist of 20 cm concrete hollow blocks. No problem. It is probably the long side exterior walls that bear the most weight.
Ok, have the same stones in my basement wall, will first check if my rafters are load-bearing otherwise it will mean hoisting a beam up in the attic. Where do you live by the way? with regard to the snow zone..
The house was built in '58 and the funny thing is that my exterior walls only consist of, from the inside: 21 mm vertical raw boards, 70x45 mm vertical (cc about 150...!) between these – horizontal 70x45 mm with mineral wool. Then comes a 15 mm thin fiberboard as a wind barrier and battens. There are no lintels above the windows (150 cm wide). The carpenters who were here and made new, larger window openings had never seen anything like it. Just to be safe, they built a new load-bearing wall inside the old one
What am I trying to say with this? Well, today we tend to over-engineer everything to the extreme. But as I said, belt and braces...
I have now consulted a constructor, and it was as I suspected .. The roof trusses are self-supporting, so there should be no problem removing the wall. However, he thought, and I agree, that it's good to have a belt and braces. I will glue and screw together 2 pieces of 2"x9" 6m long and hang the lower frame on the roof trusses that are hanging in the air, in the same way as shown in the first post. Just need to wait until I'm off the crutches.. I've managed to break my leg
How has it gone with this? It's getting close for us to do the same thing. We are planning to buy a glue-laminated beam, 56x225 and about 6500 long, at Beijer which will be placed in the attic. Do you know if there is a suitable beam shoe for the purpose?

I assume you'll have one or more posts/walls somewhere in the middle of that beam; otherwise, it might become a banana

Yes, it's getting close here too. However, I bought a glulam beam 90*225 L=6500. This will now be put in place, maybe this week...
