An Experimental Study on the Structural Capacities of Steel-Concrete Column

Seong Jae Kim, Soon Jeon Park, Sug Chang Jeong, Se-Hoon Kim

Abstract

Maximum-strength concrete-filled steel square tubular columns were tested under concentric and biaxial eccentric load. Buckling length-section depth ratio , magnitude of eccentricity e, and angle of eccentric load were selected as experimental parameters. Strength and behavior were also examined. Test results showed that the maximum strength of columns under biaxial eccentric load could be predicted using the previously proposed strength formula of columns undr uniaxia eccentric load. Likewise, the behavior and maximum strength of columns could be predicted using the analysis.
