Glued-laminated column directly on the concrete slab?

[copello2]

We are in the process of tearing down a load-bearing wall and will be installing an HEA 180 beam on 115x115 glulam columns. One column will be placed in an exterior wall, and I'm hesitant to place the column on the sill, as the fiber strength is considerably lower across it. Therefore, I'm considering cutting into the sill for the glulam column. In this context, I'm wondering if it is okay to place a glulam column on the concrete slab (solid slab in a villa built in 1988) but with sill paper underneath to prevent moisture? You certainly don't want the column to start rotting at the end...

Are you going to take giant loads?

With the right sill insulation, almost no moisture can migrate up, so you should be calm. Unless the sill next to it lacks sill insulation and you have existing moisture problems?

I believe it's about sufficient loads not to place the column directly on the sill, but that's just an assumption on my part. It seems like it would be a better option to place the column on the concrete slab with sill paper underneath.

I haven't opened the outer wall yet, but I assume the sill is correctly installed with sill insulation (sill paper) etc. And we have no problems with moisture / bad odor as far as I know.

If you're worried about the point load, perhaps the same designer who calculated the beam and columns could take a look at it? Otherwise, you could always cut out the sill and position the column on it, but an alternative could be to place a flat bar underneath the glulam column against the sill to distribute the load a bit over a longer area.
