摘　　要：进行了16个不同含钢率的钢管混凝土试件的偏心受压试验,得出了其荷载变形曲线及极限荷载。以双剪统一强度理论为基础,给出了钢管混凝土承载力的理论计算公式,并与试验进行比较,其结果基本一致,为钢管混凝土的分析计算提供了一定的理论依据。It was conducted the test of 16 concrete filled steel tubes （CFST） with different steel ratio under eccentric compression. The load-deformation curves and the ultimate loads of the samples were obtained. The formula of beating capacity for CFST was also given based on twin shear unified strength theory. Good agreement was found between the experimental and the analytical values of the bearing capacity.
