concrete column directly on the slab?

concrete column directly on the slab?

concrete column directly on the slab?

(OP)
I have a situation where a concrete column from an upper floor is directly on a concrete slab above basement. Column is pretty heavily loaded since it supports a beam on upper floor. I design some beams (marked yellow in image bellow) that are partly integrated in the slab above basement so the column lies on beams. Is that OK? Vertical loads from column can be taken by a beam, but what about bending moments from column to the slab? can I take into account that slab can take them? Any advice here or better solution?

Sadly I cant make another column in the basement bellow a column. So what do you think?





RE: concrete column directly on the slab?

Hi

You can use deep beam or transfer slab to support the column.

RE: concrete column directly on the slab?

It's just something you need to run the numbers on to know. As an alternative, could you run the column to the ground and provide a footing? Would it present a problem to have a column in this open area?

(OP)
As I mentioned, I am not allowed to run the column to the ground and provide a footing.

Also, I cant use deep beam since it would affect height of floor.

RE: concrete column directly on the slab?

Do you really need that column? Isn't it possible to create a beams only system on that location to carry the load to the adjacent column in the façade?
