| Abstract: | The fire resistance and the fire protective cover of concrete?filled steel tubular (CFST)column are studied in the paper Based on the theoretical and test results,the influence of many factors on the ultimate strength of CFST column is analyzed It includes the strength of materials,the steel ratio,the sectional dimension,the slenderness ratio,and the load eccentricity ratio The results show that the fire duration time,the sectional dimension,and the slenderness ratio have significant influence on the ultimate strength At last ,formulas for the ultimate strength and the fire protective cover of the CFST columns are proposed It can be used in high?rise building projects |
