I want to install another floor in a space that currently has very high ceilings. I started calculating freely supported beams and thought about using IPE steel beams in the outer structure against the exterior walls and then laminated wood as the joists.
However, it is quite a large space, 4x9 meters.
According to building standards, you should account for 200kg/m2 plus the dead weight of the construction, and then, as mentioned, freely supported beams with uniformly distributed load.
I'm considering IPE160 and then laminated wood 56x225. But I'm worried it will flex or make noise when walking on it. I plan for it to be without insulation underneath, so probably double chipboards, perpendicular to each other, and then the floor on top of that.
But now I'm starting to wonder if it should be cast with concrete and steel beams instead.
