column shape comparison
(OP)
If two concrete columns were holding up a beam between them (that went through the concrete), how would the following two shapes compare, structurally?
Two 8-inch cylindrical columns
-vs-
Two 12-inch half-cylindrical columns with the flat sides facing one another

Why attempt to construct a column with a half circle cross-section (unless it's absolutely required by the architect)?
Just cuz concrete can assume any shape doesn't make it easy to construct. A column cross-section like that would prove to be much more expensive to form (there are no "standard" forms for that cross-section). And, whatever form the contractor dreams up is unlikely to produce reliable results.
Although I suppose you could use half of a steel or FRP circular column form combined with a sheet of plyform bolted to it. If the circular forms are readily available in your area.
Just my NTBH opinion.
