am planning to tear down a load-bearing wall, which is 9 meters long with a column in the middle. so the span will then be 4.5 meters between the column and the wall I have a HEA 160 beam is it sufficient the beam will support the floor joists on the upper floor.
You have given us too little information to be able to calculate this.
A drawing/sketch would have been a good start.
I myself have a HEA 160 that supports my intermediate floor, so it might very well work in your case too, but as mentioned, more info is needed to determine that.
Contact a Konstruktör who can come and help you.
I would never ask a forum about how strong a load-bearing beam should be when it comes to those spans.
Too much can go wrong.
As mentioned, you need professional help with that. If nothing else, that's a reportable action (intervention in load-bearing construction). The municipality should require a construction drawing with calculations.
This includes not only dimensioning the beam but also the attachment of the beam, column buckling dimensioning, and ensuring the foundation, the basement, can withstand the point load from the beam's support points.
Just as an example: If you have 5m from the beam to the outer wall, in both directions. And nothing that loads on the upper floor, no interior walls up there, no load from the outer roof that can be transferred down to the beam.
Then the load on the pillar will be about 5 tons. Which is quite a high load.
I'm considering each 4.5m stretch as its own area. A section of the beam then handles an area of 45 sqm. Floors (in residences) should be able to be loaded with 200kg per sqm + the self-weight of the joists, assuming about 20 kg. This means the entire area "weighs" 11,000 kg. Half of that is taken up by the outer walls, half by the beam in the middle. Each support point on the beam takes up half of that, i.e., 2750kg. The post receives the same amount from the adjacent section, so the post gets "double load," 5.5 tons. This is just a rough calculation to demonstrate the need for an engineer.
If there is then any load on the intermediate joists from interior walls, and any load from the outer roof that is transferred down, you can easily reach double the load and more.
Yes, a constructor might be good. It's not very far along yet, if I put it that way.
The reason I want to do this is that the intermediate floor currently is supported by timber logs that are inside the chimney. I want to remove these logs and replace them with the beam. Since the foundation has settled after 100+ years while the chimney has remained steady, it has resulted in too much sloping on the upper floor; it's no longer charming. These timber logs are in the outer walls of the timber frame where the beam will also be placed. The pillar will stand on a cast slab.
Some weight from the roof structure will also be supported by this. The rafters rest against the outer walls as well as a long timber log that stretches from outer wall to outer wall.
I am sending along some sketches.
And of course, I am aware that I'm not getting any exact answers, I just want to get a little sense if the hea 160 beam might be sufficient or if it's completely off track.
