Behaviour of Concrete Filled Steel Tube Reinforced Concrete (CFSTRC) Stub Columns: Experiments

Yong Jin Li, Qing Xin Ren, Fei Yu Liao

Abstract

Concrete filled steel tube (CFST) reinforced concrete (CFSTRC) columns subjected to axial compression were experimentally investigated in this paper. A total of ten specimens were tested. The main parameters varied in the experiments were steel tube ratio and concrete strength. It was found that, under axial compression, the column ultimate strength increases with the increasing of steel tube ratio and concrete strength. The work in this paper provides a basis for the further theoretical study on the behavior of CFSTRC columns.
