CONCRETE COLUMN ATOP CONCRETE WALL
CONCRETE COLUMN ATOP CONCRETE WALL
(OP)
Has anyone ever shown a column coming down on a wall that is thinner than the column. Concrete columns are 14" thick and wall is 12" thick. I don't like this idea. Has anyone ever done this?

I suppose if you check concrete bearing, wall capacity with a concentrated load, and detail the reinforcement to properly lap and tie the two together that it would work. But it would look weird.
My mentors always told me that if a portion of my structure looked weird, then there's probably something wrong with it.

Unless you want to answer that or worse, have someone else answer it (maybe agreeing with the questioner), don't do it.

We'll hopefully see it in a few years in one of those random email forwards of poor construction... :)
But to be analytical about it, if 2" of the column is unsupported, is it really doing anything? I guess you could analyze it as a tapered column, 12" at the base... But its not the stress at the base that controls the column size anyway, its buckling at the middle?

What I failed to mention is that there will be a floor slab at the column / wall interface. That being said, the appearance probably wouldn't be as bad since it is hidden by the floor slab.

No actually I think they are your speciality!
I wouldnt see a problem with it if the bars could be made to work.
I would suggest that you allow for the 1" eccentricity and distribute this between the members according to stiffness and ensure the reinforcement can take it.
I would also suggest you check the slenderness of the wall for issues and the interface stresses if the wall and slab are a weaker concrete than the column.
