| 摘 要： | 通过对9个不同尺寸和壁厚的内圆外方的复式钢管混凝土柱试件(其中内(圆)增强方钢管混凝土试件6个,方中空夹层钢管混凝土试件3个),进行偏压试验得到极限承载力和荷载-变形曲线。试验表明,对内(圆)增强方钢管混凝土,内置圆钢管的存在能够对偏压方钢管内核心混凝土起增强作用,且这种增强作用随着圆管管径的增大愈加明显;对于方中空夹层复式钢管混凝土偏压短柱,随着圆钢管管径的增加,其承载力降低的程度愈大。

| Abstract: | The 9 multibarrel tube-confined concrete column specimens with square hollow section in the outer and circular hollow section in the inner(SHS in the outer and CHS in the inner) were prepared,of which 6 concrete-filled square steel tubular specimens reinforced by inner circular steel tube and 3 concrete-filled double skin square steel tube specimens.The results show that the circular hollow section has a reinforced effect on concrete-filled square steel tubular specimens reinforced by inner circular steel tube.With the diameter of inner steel tube increased,the ultimate capacity of concrete-filled double skin square steel tube columns is reduced soon. |

| Keywords: | reinforced by inner circular steel tube double skin concrete-filled steel tubes eccentric compression experimental investigation |
