Abstract

Nowadays high-rise buildings and multi-storey buildings are more common and popular, they require highly strong and efficient structural system. Concrete Filled Steel Tube [CFST] are capable of providing the same. Many innovative ideas are being put forward in the improvement of the CFST section, which resulted in better improvisation of their column behaviors. Diagonal rib stiffened square concrete filled steel tube can increase the confinement, load-carrying capacity and ductility compared with the CFST specimens without stiffeners. By introducing the diagonal rib fitting, the composite effect of the square concrete filled steel can be improved, which is proved from the previously conducted experiments by several researchers on CFST sections. By analyzing the test results from experiments, a cost effective, robust and safe designed cross section is developed. The development of an analytical model for the CFST with diagonal ribs for predicting their axial load carrying capacities was done by finite element analysis method. It helps in predicting the results of combinations made by using various parameters.
