•Experimental study on circular CFST under long-term bending and chloride corrosion.•Full-range analysis of circular CFST under long-term bending and chloride corrosion.•Simplified model for ultimate flexural strength of corroded circular CFST.
This paper studies the flexural behavior of circular concrete filled steel tubes (CFST) under sustained load and chloride corrosion. 7 CFST specimens were tested under a four-point bending load. It was found that corrosion causes noticeable deterioration to the flexural strength, while the ductility of CFST keeps well. A finite element analysis (FEA) model was developed to study the full-range behavior of CFST under corrosion. A parametric study was conducted to find the main parameters that influence the residual flexural strength, based on which a simplified model was proposed to calculate the residual flexural strength of circular CFST under long-term load and corrosion.
