Hello!
My desire is to create a space under an extension. "Right underneath" there is a support (which must be removed).
I plan to replace this support with a glulam beam / HEA beam (or similar).
How can this beam be calculated / installed?
The wish is for a solution with the lowest possible construction height.
The beam must also not be "too heavy."
Tried to find a solution on byggbeskrivningar.se (regarding glulam beams)
https://www.byggbeskrivningar.se/dimensionering/oppning-innervagg-2-planshus/
But I don't know if my desire involves the same calculations. (Today, the lower floor and other trusses do not exist)
One thing is the strength of the beam, another is the support for the floor joists (which are currently resting on a stone - maybe 20-25 cm?) Does the beam need to be just as thick?
Background:
The extension is about 8 x 4m (crawlspace foundation). Haven't measured - As mentioned, there's a row of stones almost in the middle of the building.
The floor joists rest on these stones.
Uncertain if there is an interior wall (or possibly a half interior wall) directly above these stones.
I've tried to analyze if the roof/trusses can rest on some interior wall. (but I don't think so)
A truss roof - W truss shouldn't need any support over an 8m span.
This would mean that it is floor joists / a tiled room (toilet) / some interior wall that would rest on this beam.
