组合截面压杆的受力性能
|
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.
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.
