According to ETABS 9.7.0, following are the rules where it calculates the beam column capacity ratio:
Rules: Beam-column capacity ratio is only determined for a station
a) if the station has a beam-column joint (top of the column),
b) if the frame is a ductile moment resisting frame,
c) if the column above is a concrete column when it exists,
d) if all the beams framing into the column are concrete beams,
e) if the connecting member design results are available, and
f) if the load combo involves seismic load.
Kindly check your model for above.
