Calculate maximum point load slab?

[Strip]

Is there anyone who can/wants to help me calculate roughly how much point load my foundation slab can be expected to withstand?

The foundation is constructed as follows:

Cement: 100 mm "C28/35 16 S4 Std. Cem"
Reinforcement: 6150 nk500ab-w (about 55 mm from the surface)
Insulation: 3 x 100 mm EPS S80
Crushed stone 8-16 approx. 200 mm
Clay

I have a glulam beam that is to be spanned with a pillar roughly one-third of the length. The builder has calculated the point load to 37kN, but I believe it might be slightly underestimated as neither snow pocket nor attic storage appears to be included. At each end of the glulam beam stand 2 screwed-together 45x95 C24s, and the idea was to have the same construction on the central pillar, but I'm leaning towards a slightly stronger pillar. The pillar stands within a wall, so I can to some extent distribute the load sideways across the glulam beam.

These kinds of calculations are not my specialty, but what I arrive at for a 100 mm slab is not anywhere near 37 kN, more like half.

The reinforcement you have (6150 reinforcement mesh) is only for crack reinforcement in the slab. I haven't calculated the whole thing, but I find it hard to see that the slab can withstand that point load without a haunch with extra reinforcement and concrete.

Do you have any information on how the edge beam is constructed?

Well, I don't have the exact measurements, but I know it's 200 mm high. I guess about 200 wide at the top and 100 mm below the first layer of 100 mm insulation. A 10 mm iron at the bottom, and one at the top along with the mesh.

But the edge beam is probably not going to help me much, it's two meters away. But I should be able to place a support beam across the glulam beam, in the wall, to distribute the load over a larger area. I have about 330 mm to spare in height, so there's room for something substantial there.

I have found that the slab can handle a point load of about 18 kN on 95x95 mm, is that a reasonable figure? Does it matter that it's a short-term (winter, snow) load?
