摘要：

Experimental research on bearing capacity of concrete filled Steel tubular ( CFST) compression members indicates that the sectional dimension, concrete compressive strength, steel yield strength, slenderness ratio, sectional steel ratio, load eccentricity ratio, initial steel stress etc. are the factors influencing the bearing capacity of CFST compression members. To calculate correctly the bearing capacity, grey system theory is used to conduct a grey correlation index analysis on the bearing capacity and relevant factor of CFST compression members. The result shows that the main factors influencing bearing capacity of circular CFST compression members are confinement coefficient and slenderness ratio, secondary factors are initial steel stress and load eccentricity ratio; an( the main factor influencing bearing capacity of square CFST compression members is confinement coefficient, secondary factors are load eccentricity ratio, initial steel stress and slenderness ratio.
