| Abstract: | Factors that influence fire resistance of circular concrete-filled steel tubular (CFST) columns were analyzed using the grey relational analysis method of grey system theory in this paper to distinguish the importance of each factors,the analysis was based on test data on fire resistance of 18 circular CFST columns.The results indicate that the sequence of correlation factors influencing the fire resistance of CFST columns is fire protection thickness,fire load level,section dimension,slenderness ratio,stee... |
