Performance and calculations of concrete filled steel tubes (CFST) under axial tension
Abstract This paper reports the behavior of concrete filled steel tubes (CFST) under axial tension. A total of 18 specimens were tested. The main parameters were steel ratio, concrete type and bond or unbonded between the steel tube and its core concrete. A finite element model (FEM) was developed to perform mechanism analysis and parametric studies for CFST under axial tension. It was found that the tensile strength of steel tube can be increased due to the existence of the core concrete in CFST. Finally, a simplified formula that can predict the tensile strength was proposed.
Research highlights ► Concrete filled steel tube (CFST) under tension. ► Experimental performance under different parameters. ► Finite element model (FEM) for mechanism analysis. ► Parametric studies. ► Simplified model.
