Abstract
Steel members have the advantages of high ductility and tensile strength, while concrete members have the advantages of high compressive strength and fire resistance. Composite members made from steel and concrete, have the beneficial qualities of both materials. Concrete filled steel tube column is a recent concept. Concrete filled tube columns provide higher stiffness due to confined effect as compare to hollow steel tube column. Very few research works are conducted on concrete filled steel tube short columns. It is observed that this type column has more load carrying capacity. In this paper experimentation is carried out on three hollow specimens and nine specimens are concrete filled steel tube with variable ratio of diameter to wall thickness. All the composite column specimens tests are carried out under Universal Testing Machine.
