Hello!
I know there are some threads about the choice of glue, but I can't seem to find a perfect answer, so here comes the question again
What glue would you use for gluing studs/joists that will be part of a load-bearing structure?
In an old house where the floor joists among other things are rotten, I will build a robust joint around the parts that need splicing where the entire studs can't be replaced, and I want to glue these in addition to screws/nails to achieve maximum load-bearing capacity.
Any tips?

Use regular wood glue. I buy mine at Biltema and it has worked perfectly for gluing both joists and various types of glued timber constructions.
Hello!
What I've tried to learn is that wood glue becomes a bit too "hard", meaning it has no flexibility without cracking in the joint, unlike something like PL400.
On the other hand, maybe it's precisely flexibility that you want to avoid and for it to be completely rigid?

there are no "mute" wooden houses anyway so skip the glue you.
Wood glue is not flexible; as long as the grain direction is the same, both parts will swell and shrink approximately the same amount, so it’s fine to apply glue. If the grain direction is different, it’s better to skip the glue, as the wood will move too much, and the glue will come loose. Instead, make a good screw joint. Can you describe a bit more in detail what you are repairing (or even better, upload a picture).
Hello!
Ok, thanks for that, it explains a lot
Now, this was already done yesterday and I lifted up a bit more of the floor so I could make a parallel floor joist along the entire length of the "rotten" joist, so this turned out really well anyway
But if we think about the next step, I need to replace a number of posts that are currently 100x100 in dimension, supporting these floor joists. I'm thinking about gluing together two 95x45 to replace these. If I understand this correctly, would regular wood glue be the best option to make this as strong as possible?

if the weight is distributed evenly on the two parts, it might be sufficient to just screw there as well. After all, it's just a point load in the longitudinal direction.
