No, preventing buckling is a significant advantage provided by filling a
steel column.

Uh, yes. And the buckling it prevents would be the result of fire. Filling the
columns with cement is to protect the columns from buckling in a FIRE.

It also adds tremendously to normal buckling resistance, not just
buckling resistance due to fire reducing the capacity of the material.
