摘要/Abstract

摘要： 研究组合截面短柱轴心受压的截面应力和紧箍力分布规律.通过理论计算模型推导了组合截面圆柱应力分布的解析解；建立了有限元数值分析模型，考虑材料泊松比、管壁壁厚等参数的变化，验证了圆形截面应力分布的解析结果，并得到了方形截面应力分布的规律和存在有效约束区的特点，为组合结构构件的受力性能分析提供理论依据.

Abstract: This paper analyzed the distribution of combined cross-section of short column with axial compression stress and contact stress. The analytic solution of combination of crosssection of short circular column was derived first and validated by numerical simulation, considering the material’s Poisson ratio, wall thickness and other changes of parameters. Then the paper analyzed the square cross-section with more material of column based on the circular research, providing theoretical basis for analysis of combined structure under certain force.

Key words: plane strain, combined cross-section, axial stress, contact stress
