Hidden beam during extension

[dogpox]

Anyone know if this is possible? Two-story house, opening around 5 meters, with an intermediate floor resting on the exterior wall that is to be removed. Are there solutions to avoid a beam at the opening on the ground floor?

Anyone know if this is possible? Two-story house, opening around 5 meters, intermediate floor resting on the exterior wall that is to be removed. Are there solutions to avoid a beam at the opening on the ground floor?

Definitely possible,
I was involved in demolishing a load-bearing basement wall a few years ago when the homeowner also wanted to expand the basement.

The reinforcement in that case was an HEA200 steel beam as seen in the pictures below. Span of about 6m.
It was completely integrated into the floor structure as we cut the existing floor joists into the beam, which is somewhat visible at the top of one of the pictures.

This could be a type of alternative if you don't want a visible beam.

I think I understand the construction, but I wonder if such a beam is intended to be used that way? Did you calculate the strength and the loads that press between the beams?

In this case, it was a designer who developed the detailed drawing of this solution. So I'm completely sure it will hold. It's basically just the load from the floor that stresses the beam.
The result was an entirely rigid floor.
