N2 - This paper proposes the new strength formula for the CHS column to H-beam connections stiffened by exterior diaphragms in which the effect of material strength and geometric properties are unified. In order to derive the strength formula, limit analysis based on upper bound theorem was performed. Since the theoretical solution is too complicated to use in practice, the unknown variable to define the yield line in collapse mechanism was approximated by means of parametric study to develop the practical strength formula. The validity of the strength formula was verified in comparison to FEA and previous test results.
