Sizing of load-bearing beam

[prototypen]

Can you not set the beam 9 mm at an angle to make it float towards both walls?

Becomes an LT beam.

90*360 but then I lose in height
115*315 but how do you build it in and "posts" so it looks nice?!
can you place a 115*315 on 90*90posts?

My 115*315 beams rest on 115*115posts...

When it comes to columns, it is generally buckling that is dangerous.

Here is something to go on.

I have a buckling length of 2.5 meters, and then 115x115 is needed to handle 65kN, which applies to the middle pillar.
Then maybe I'll build it into a wall, and thereby might reduce the buckling length a bit, but it feels good that it can stand alone and see the rest as additional safety margin.

No, I drive a Toyota

Is there anyone who can recommend a constructor/structural engineer who can calculate a beam?

We are also interested in tearing down part of a load-bearing concrete wall and replacing it with some type of beam.

Edit: between northern Stockholm or Uppsala /Tony
