I have removed the ceiling in the basement and there is a floor joist spliced with a relatively thin u-steel profile underneath, 3-4cm. The whole thing is sagging a few cm and I was thinking of reinforcing everything by installing a new HEA, not necessarily lifting everything because who knows what I might break inside the house (which, by the way, is just a shell at the moment).
The span is 2.5m and I have very little sense of the strength of beams... a 100HEA could be put in and wedged so it rests on the foundation walls. How much can this hold if it has pressure in the middle? I've read up on this and the answers are quite complicated... "You need to calculate the deflection" and so on... But I just want to get a rough idea about strengths so I can make a safe overestimation.
Can anyone tell me if that's what's required for, let's say, 1-ton pressure in the middle of a 2.5-meter beam that has a bearing of 10cm on each end? Does a HEA 100 work?? 2 of them?? a HEA 140, HEA 200...??? I have no idea...

How thick is the floor structure?
Isn't it possible to just glue and nail plywood on each side of the existing beam?

On top is a wooden floor in a small room with a span of 2.3m and floor joists (old timber logs) with varying center-to-center distances of 50-80 that support it. Then there is an interior wall with unknown pressure on it, but it seems to have some bearing capacity. 1 ton was just a number I threw out there to get a feel for what a hea 100 can handle.
Maybe it works to just glue and nail plywood, who knows... I just want to overdo it just enough so I can be sure it holds up to 110%.
