摘　　要：为研究钢骨-钢管高强混凝土偏心受压柱的力学性能,采用ABAQUS有限元软件分析偏心距、长细比、材料强度等因素对压弯柱力学性能的影响,并对数据回归分析以建立承载力公式.结果表明:基于ABAQUS软件所模拟的荷载-变形曲线与试验曲线吻合良好;偏心矩、长细比对偏心受压构件的受力性能影响较大,套箍率影响次之,材料强度和型钢截面形状对其影响相对较小;偏心受压承载力公式计算结果与试验结果吻合良好.To analyze the mechanical properties of steel tube filled with steel-reinforced high-strength concrete （STSRHC）column under eccentric loading,analysis of eccentricity,slender ratio,material strength on eccentrically com-pression were conducted by the finite element software ABAQUS,and the formula of bearing capacity were establish by regression.The ABAQUS calculation results agree well with and experimental ones.Slender ratio and eccentricity influ-ence significantly the eccentrically compressed mechanical properties,the influence of stirrup ratio is less than the influ-ence of slender ratio and eccentricity,and influence of the material strength and the shape of steel is the smallest;the cal-culation results by the formula are in good agreement with the experimental results.
