Concrete-filled steel tubes (CFST) have been increasingly used in the construction industry due to their favorable structural performance. CFST is a component with good performance resulting from the confinement effect of steel with concrete. The confinement methods can postpone the local buckling of steel tube and enhance the
concrete confinement strength provided by the steel tube. Given the fact that the ductility and energy dissipation capacities of CFST columns are of paramount importance in earthquake-prone areas, the cyclic behavior of these elements has earned the attention of several authors. Due to their excellent strength, ductility, seismic performance and fire resistance. This paper aims to present a review about the investigation done on cyclic behavior of concrete filled steel tube columns by various researchers. The reviewed studies include circular and rectangular and square cross-sections. Members with normal strength concrete (NSC), high strength concrete (HSC), as well as ultra-high-strength concrete (UHSC) infill are all included. A consensus of the results shows that CFST members have superior resistance to cyclic lateral loading.
