Replace column with beam and two columns

[Flopgunder]

Hello,
I have used the dimensioning tool on traguiden.se to make the calculations for my planned shed with a ridge beam. I have a fairly wide window leftover from the house when we installed patio doors in another place. The window requires a module width of 214 cm, and I would like it centered on one of the gables. Therefore, I need to find a way to support it since a post in the middle is not an option.

I actually found a thread with an almost identical problem here on the forum: https://www.byggahus.se/forum/threa...etta-garageport-under-baerande-pelare.397169/
And the conclusions I draw from that thread are that my suggested dimensioning of a glued beam at 115x315 should be fine. The question is essentially: can the beam with that span support a load of 18.8kN in the middle? But does anyone have any good references to tables or the like? I find it hard to find anything like that.

With that dimension and span, the beam can handle 100 kN or about 10 tons as a point load in the middle. You can go down to 115x225 and still have very limited deflection if the point load is 18 kN. There are no tables for this kind of thing because there are too many variables. But it's easy to calculate.

Thanks for the answer, it seems I've been a bit overambitious, but if I reduce it a bit, it'll be perfect.
