Abstract

This paper presents the behavior of concrete-encased CFST stub columns under axial compression after exposure to fire from both experiment and numerical analysis. ABAQUS is used to develop a finite element analysis (FEA) model to investigate the performance of the composite columns after exposure to fire. Two groups (10 specimens) of concrete-encased CFST stub columns with different CFST ratio and fire duration time were tested. The FEA model was verified by comparison with test results. The work of this paper provides a reference for further theoretical study on concrete-encased CFST stub columns after exposure to fire.
