摘要: 通过对9根圆钢管混凝土短柱试件的试验,首先对其破坏现象及机理进行分析;然后分别探讨混凝土强度、长细比、偏心率三个因素对该类构件力学性能的影响规律,指出偏心率是影响该类构件力学性能的主要因素,短柱范畴内的长细比及大偏压中的混凝土强度影响不明显;并针对该类构件在实际工程中的应用提出建议。

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.
