Abstract: This paper presents the results of analytical, numerical and experimental work of steel encased composite column using Alccofine concrete. In practice, most of the composite columns are relatively slender in nature. In composite column there is no requirement to provide additional reinforcing steel for composite concrete filled tubular sections and in composite column both the steel and concrete would resist the external loading by interacting together by bond and friction. In order to increase the strength, durability of the column and used to reduce the water content for the concrete mix, Alccofine a new type of a mineral admixture is added with the concrete mix. In this paper comparisons will take place between the conventional column with the steel encased composite column with Alccofine which results in higher strength and resist the sudden failure when axial load acts on the specimen. The sections are arrived by using the code IS 808:1989. The finite element software (Using ABAQUSE software) is used to determine the numerical analysis of the composite column under axial load and finally, the ultimate plastic resistance of the composite column is compared with analytical, numerical and experimental works.
Keywords: Alccofine, steel encased composite columns, Mineral admixture, strength and durability, friction.
