: Steel concrete composite systems have been widespread use in recent decades because of the benefits of combining the two construction materials. Reinforced concrete is inexpensive, massive and stiff, while steel members are strong, light weight and easy to assemble. In composite columns there are two principle types, Steel Reinforced Concrete (SRC) where a steel section is encased in concrete fully or partially and Concrete Filled Steel Tubes (CFST). Indian standard codes IS: 11384 (1985) and IS: 3935 (1966) for Composite Constriction have not covered the design of for uniaxially loaded steel concrete composite columns. Recent code IS: 800 (2007) has also not furnished the limit state design of composite columns. Therefore to design composite columns we need to go for different codes in use worldwide. EC 4 (2004) gives plastic stress distributions at different point in interaction curve for Uniaxially loaded composite column. ACI-318 (2005) gives strain compatibility method to draw interaction curve for Uniaxially loaded composite column. American Concrete Institute (ACI)-318 (2005) and Eurocode (EC) 4 (2004) design approaches for Uniaxially loaded Steel concrete composite columns are compared for Previous experimental studies. The ratio of Test/ Code is compared with concrete strength, steel strength, percentage of steel and width to thickness for both codes.
