Analysis of steel-reinforced concrete-filled steel tubular and concrete-filled steel tubular columns under cyclic loading

In recent decades, concrete-filled steel tubular (CFST) and steel-reinforced concrete-filled steel tubular (SRCFST) structural members have been widely used in the construction of modern buildings and bridges. However, there is a limited finite element analyses and experiments under cyclic loading....

These composite constructions ideally combine the advantages of both steel tube and concrete, namely the speed of construction and high strength. Moreover, they have lighter weight, higher bending stiffness, and better cyclic performance than the reinforced concrete construction. In this respect, a new form of composite column, steel reinforced concrete filled steel tubular column (SRCFST), has been proposed to further enhance load capacity, stiffness and cyclic performance.
