摘　　要：为了研究不同参数对组合短柱在轴心受压作用下的力学性能影响,采用ABAQUS数值模拟软件对钢管混凝土柱进行了参数化分析,研究的主要影响因素包括钢管径厚比、钢管屈服强度等级、混凝土强度等级、混凝土泊松比、组合柱截面形状、钢管外壁四周围压。根据数值模拟结果,总结不同参数对组合短柱力学性能的影响规律,为今后钢管混凝土组合柱的研究及工程实践提供参考。In order to research the mechanical properties of combined short column under the pressure of axial center,the parametric analysis of concrete filled steel tube columns using ABAQUS numerical simulation software,the main influencing factors of the analysis include the high thickness ratio of steel pipe,yield strength grade,concrete strength grade,Poisson ratio of concrete,and surrounding pressure of steel pipe outer wall.According to the numerical simulation results,the influence of different parameters on the mechanical properties of combined short columns is summarized to provide reference for the future research and engineering practice.
