Abstract

Abstract

The experimental study on the 9 short CFST columns is conducted.On the basis of which,firstly,the failure phenomenon and mechanism analysis are conducted;then,the influence of the concrete strength,slenderness ratio and eccentricity ratio on the mechanical behavior of this sort of member is analyzed,which indicates that eccentricity ratio is the main influence parameter,the slenderness ratio in the range of short column and the concrete strength in the large eccentricity pressing have little effect on the behavior of this sort of member.And the rational suggestion is given on the application of the member in actual projects.
