I am wondering if there are studs hidden that support the beam in the construction, or if the beam itself is free-standing. The house is 10x10 meters. 1 1/2 floors + basement and a gable roof. A cross beam 250x100 parallel to the rafters. The question is more about whether it is possible to remove the wall which is 2100, which would make the beam span 4300mm freely. The height from the floor to the beam is 2150. I will remove the drywall so we can see how it is framed within a week or two. Any spontaneous ideas?
You can start by calculating backwards. What load can a 10 m long glulam beam with the dimension 100x250 handle? The answer is a maximum of 40 kg per meter. It is therefore definitely not self-supporting across the entire span. Can it then bear over an opening that is 4.3 m? The answer is yes, if the load on the beam is at most 500 kg per meter. It feels like a borderline case. I would need to see a better sectional drawing to assess it.
Keep in mind to submit a notification of change in the load-bearing structure to your municipality; if it doesn't hold, you might be left without valid insurance.
