Concrete filled steel tubular (CFST) members utilize the advantages of both steel and concrete with hollow steel sections. They are widely used in high-rise buildings as columns and beam-columns and as beams in low-rise buildings where efficient structural system is required. Usually in concrete-filled steel tubular columns, the local buckling of the steel tube normally occurs after the ultimate strength of the composite member is reached. Several authors suggest using the plastic moment capacity of the steel tube as a lower bound for the strength of a CFT in pure bending. A limited number of tests have been performed. to study the ultimate strength of concrete filled steel tube beams. To compare the deflection of steel-concrete composite beams with conventional concrete. M20 Grade of concrete is used as infills in hollow steel tubes and the concrete mixing is done for one batch. To determine the ultimate moment carrying capacity and deflection of the section under pure bending done by flexural test of empty rectangular steel tubes, concrete filled steel tubes and concrete filled steel tubes with diagonal stiffener. The experiment test results are compared with analytical results, To develop finite element analysis model of the concrete filled steel tubes, ANSYS WORKBENCH software is used.
