Tests on fiber reinforced concrete filled steel tubular columns
S. Ramana Gopal and P. Devadas Manoharan

    This paper deals with the strength and deformation of both short and slender concrete filled steel tubular columns under the combined actions of axial compression and bending moment. Sixteen specimens were tested to investigate the effect of fiber reinforced concrete on the ultimate strength and behavior of therncomposite column. The primary test parameters were load eccentricity and column slenderness. Companion tests were also undertaken on eight numbers of similar empty steel tubes to highlight the synergistic effects of composite column. The test results demonstrate the influence of fiber reinforced concrete on the strength andrnbehavior of concrete filled steel tubular columns.
Key Words
    composite column; hollow steel tube; fiber reinforced concrete; slenderness ratio; eccentricity; ultimate load; ductility.
