The flexural strength of a beam web joint connected to a concrete filled circular steel tubular column was calculated by the mechanism method assuming plastic collapse mechanisms of column skin plate and the beam web end. The flexural strengths of the beam web joint connected to the circular CFT column and those of a beam web joint connected to the hollow circular steel tube were compared. The flexural strengths were greater when the beam was connected to the CFT column and the strengths decrease as the aspect ratio increase. The simplified formula for calculating the flexural strength of the beam web joint connected to circular CFT columns was presented.
