Concrete Filled Column in High Rise Buildings: A Review

In the concrete-filled steel tube (CFT) columns, the interaction between the steel tube and concrete local buckling of the steel tube is delayed by the restraint of the concrete, and the strength of concrete is increased by the confining effect of the steel tube. Extensive research work has been done throughout the world. In this paper the available literature for the use of Concrete Filled Columns in high rise building construction has been reviewed. Shear connectors are important for the CFT column and comparative study with different type of specimen have been reported in this work. The use of ultra high strength material modifies the behaviour of CFT column and such study is also presented in this work. Behaviour of CFT column under flexural loading and eccentric loadings has been also reviewed in this work. It has been shown that CFT columns have better performance as compared to normal columns to sustain load during fire. Further, it has been reported that CFT columns with ultra high strength concrete are capable of resisting high static loaded at elevated temperature. It has been also indicated that use of shear connectors with circular column has resulted in improvement in behaviour of composite column subjected to the eccentric loading.
