Hello!

I have a wagon shed that I want to remove respective compartments to create a large space. Is there anyone skilled in calculating beams and loads?

More pictures will come...

So it's all posts that are in the space supported by 4 trusses that should be carried with a suitable beam (hopefully). See image 1
The roof slope is about 34 degrees with trp20 as cladding. More pictures of the roof structure will come.
Location in the country is Södermanland, so no insane amounts of snow.
The majority of beams in the building are timber 150x150.

The idea is to place a beam from side to side (8.65m) and reposition the existing posts at the wall line instead.
See image 2.

The building is about 8.65x17.8m = 153sqm

Fun computational task. The new beams are supposed to "only" take two point loads from the roof structure itself. The question is how much the roof structure weighs? It's probably safest to slightly over-dimension. In any case, they will be quite hefty beams. When I make an estimate, I end up with at least 190x540 glulam. The dimensions of the new columns mainly depend on their height, which is not specified. There are alternative solutions, such as using truss rafters, but they probably involve bigger modifications to the current structure.
 
Yes, it’s true that the load will only be at the wall line. The idea was to bolt the current 150x150 columns as support for the glulam beam running across.

I'm not surprised at all, actually. I've gotten a bit interested in used glulam 140x800, which I might be able to acquire, and they are huge beams that should work quite well. A bit less in width but significantly thicker in height.

It would have been fun to reinforce each truss today, but they look a bit odd since they lack a top chord, making a "w" or "ww" truss a bit tricky.

See the following picture of the sick paint skills on a possible solution and the height of the new columns.

So, the red are the new columns and green is the new glulam beam. Everything else is existing. The plinth sticks up a bit, so the free height is 3m, which still feels quite airy and sufficient for storing various things.

140x800 is indeed superb and much better than 190x540. If the length of the columns is only 2.5 m, any glulam dimension will do, but it's probably good to choose 140 wide so that the beam width matches. 140x135 is a standard dimension for glulam posts.
