Hello
I have a two-story house with apartments. Floor joists 50x190 cc600.
I don't see any noticeable sagging or deflection. But changing usage from a living room to an apartment.
The floor will be heavier with two new layers of gypsum and 22mm floor chipboard.
The current joists are spliced over the blue wall. I will move parts of the load-bearing wall in the future (red).
The plan is to reinforce with 45x195 C24 (blue) glued and screwed to the old beam. From both directions, it will be partially overlapping, double-sided reinforcement. On the new joists, the floor chipboard will be glued and screwed.
- Is this a good solution?

Thanks in advance.

I'm not entirely sure what you mean by blue or red wall. Clearly, an adhered and screwed 45x195 is a good reinforcement. 45x195 + 50x190 and screw-glued 22 mm floor chipboard provide good deflection values up to a span of 3.9 meters.
 
Thank you.
The span is now approximately 4.4m. (Will be 3.9 if I move the load-bearing wall in the future)
Letting the left reinforcement beam extend a few meters past the load-bearing wall. Does it provide any added value?
