Hello!
I am in the process of building a leisure house using timber frame construction.
The walls are constructed with 45x145 studs with a recessed 220mm support beam (c24) under the wall plate.
I have three openings of 175 cm each and am now considering if the recessed support beam is sufficient.
The roof is a shed roof (metal), low-sloped at 8 degrees, and the span is about 5 meters, snow zone 2.
I've tried using the calculations available on byggbeskrivningar.se but can't find one that fits. The lowest roof pitch you can specify is 14 degrees and for a gable roof.
I assume that the 220mm support beam is sufficient, but as the English expression "assumptions is the mother of all f-ups.." suggests, it would be good to have the facts

I assume the trusses are spaced with a center-to-center distance of 1200 mm. The worst-case load scenario must be if a truss lands in the middle of an opening of 1.75 m, which your beam, according to my quick calculation, can easily handle.
No.
