Hello! New here on the forum,
I'm working on a kitchen renovation and during the demolition, I found a ceiling beam that was very rotten and needs to be replaced. What should I consider when replacing the beam? The beam goes into the wall at marking A where there's a hole the old beam goes through, and on wall B, the beam runs along the entire wall and is fine, so I was thinking of splicing the beam there, is this okay?

To add, there is an upper floor.

If I've posted this under the wrong category, I'll remove the post.

Welcome!

Generally, when replacing, it is important to offload the beam and then ensure that the new beam continues to provide adequate function, so it's important to understand what it does before you start tearing it down.

Are you thinking of replacing part of the beam or the entire thing?

In general, when replacing, you should relieve the beam and then ensure that the new beam provides continued full functionality, so it's important to understand what it does before you start tearing it down.

Are you planning to replace a part of the beam or the whole thing?
Thanks
Yes, I have plenty of supports, but I'm very unsure about where to place them. From the looks of it, it doesn't seem like there's much pressure on the beam considering how rotten it is. I was thinking of replacing a part of it, up to about halfway of wall B.

Not a great picture but you can at least see that it's pretty bad
 
For the prop to be effective, it needs to be placed so you can take the load from the floor above - I assume there are some beams across as well? Then these are the ones the prop should take load from. To capture multiple beams per prop, you can use a temporary beam and place props at the ends, for example. It depends, among other things, on the load each prop can take and which beam you use.

If you are going to replace part of the beam, the joint must also be designed so that the load can be transferred to the support in the wall.

What type of flooring is in the kitchen? It's important that it can handle the pressure from the prop, so it doesn't break.
