Hello!

We are about to renovate our house and want to remove a load-bearing wall between the kitchen and dining room.
I've read a number of threads here on the website and seen that there are many knowledgeable people who might be able to give their perspective on the matter or recommend someone.

The intervention involves removing a load-bearing wall in a 60s wooden house spanning 4.6 meters.
I've calculated using the Svenskt trä's calculation program and determined that it should work with a Glulam 115×495 GL30c, deformation 9 mm (L/503), utilization rate 62% on 2 Glulam 90×90 GL30h, utilization rate 72%.
But the ceiling height is 2.4 meters and I would rather not be bent over in the kitchen, so my question is if it's possible to convert glulam to a steel beam using some formula to reduce the beam height? An HEA/B 180-200 for example?

The width of the house is 8000mm, with measurements to the load-bearing inner wall at 4000mm. 45 degree roof slope.

Grateful for any help we can get!
 
It should work with a considerably smaller steel beam, a ballpark guess, I would think you could manage with a 180mm high steel beam, or less.

But you should/must hire a structural engineer who can calculate exactly what is right in your case. You will still need to submit structural calculations to the municipality in connection with the building notification. You also need to check if the foundation can withstand the point load from the columns.
