摘要

摘要: 通过对6根方中空夹层钢管混凝土试件在双向偏压受力状态下力学性能的试验，以研究长细比、偏心距和偏心角对试件力学性能的影响。试验结果表明：试验过程中构件变形基本符合平截面假定；长细比和偏心距越大，承载力越小；偏心角对构件的荷载-变形关系曲线的影响不大。最后，采用纤维模型法编制程序，对双向偏压构件的荷载-变形关系进行计算，计算结果与试验结果符合较好。

Abstract: Six concrete filled double-skin steel tubular (CFDST) columns were tested under bi-eccentric loading condition,in order to study the effects of slenderness ratio,load eccentricity and load angle on the mechanical behavior of the specimens. The test results show that the deformation of the specimens agrees basically with the planesection assumption; the larger the slenderness ratio and load eccentricity,the lower the bearing capacity; load angle has little effect on the load-deformation relationship curves. Finally,load-deformation relationship curves of CFDST subjected to biaxial compression are analyzed by fiber element method. The calculated results are compared with the experimental results,and they agreed well with each other.
