Building Concrete Columns in the Soil
(OP)
Will a concrete column supported by soil buckle? Can we say that the effective length factor K=0 for this condition and therefore makes the critical buckling load Pcr undefined?

Once buckling commences, the forces are pretty large. A small lateral movement is all it takes to get it started. To activate even the active pressures, takes more movement than it would take to start buckling.

But sometimes we have to support a structure with columns below grade. This happens when there's a building or a portion of a building constructed on a deep excavation. Before the excavation is filled, we have columns constructed on footings and the backfill installed around them.

Continuous bond beams would seem to be a good idea above and below each opening and at floor level.
