dimension of steel beam

[Enk Projektet]

It's load-bearing

If so, it will only be 5.5m as the span.....

No, but on the joist... and that's what you want to be as rigid as possible... also look into a solution with thicker joists, which will make the steel beam smaller...

Yes, if the wall between the storage and garage is load-bearing then the free length becomes 5.5m. And as Erik Projektet writes, if you increase the height of the intermediate floor, the deflection of the floor joist decreases and then requires a smaller steel beam.

Go up to 220x45? What I was thinking is that if the beam is swaying, the fact that it's made of wood doesn’t matter. It will be shaky either way.

My calculation is based on TS's sketch and information, where the beam is 9m long and the floor area that loads the beam is 9x7m. As I interpret the sketch, the storage wall is load-bearing; otherwise, it would be a larger floor area loading the beam.

I think you're right Gabbe1

Brain glitch on my part: I have 3.40 from the flat surface to the finished floor on the upper level. So a sturdy beam will fit:
