Abstract
This paper develops a finite element analysis (FEA) model to simulate the behavior of concrete-encased CFST columns under combined axial load and fire including heating and cooling phases. Experimental data, including concrete-encased CFST column tests at ambient temperature, CFST column and RC column tests in fire and CFST column tests after fire, are used to validate the established FEA model, and generally the accuracy of predicted results is acceptable. Based on the FEA model, the temperature distribution, failure mode and deformation of the concrete-encased CFST column in heating and cooling phases are investigated. Finally, a parametric study is conducted to investigate the influence of various parameters on the performance of concrete-encased CFST columns failed in cooling fire.
