Finite Element Analysis of Axial Compression Properties of Steel Square Tube Composite short Columns Filled with Unsymmetrical Type Steel-Reinforced Concrete

  • 摘要: 采用有限元方法对8根非对称型钢骨-方钢管混凝土组合短柱的轴压性能进行分析,研究组合柱在轴心受压全过程的荷载-位移关系曲线,分析混凝土强度、配骨率以及套箍指标等不同参数对组合柱轴压性能的影响,为实际工程技术提供相关的参考与建议。研究结果表明:这种新型的组合短柱具有良好的轴压性能。

     

    Abstract: The finite element analysis method was adopted to conduct the axial compression properties of steel square tube composite short columns filled with 8 unsymmetrical type steel-reinforced concrete. Moreover, the load-displacement curve of the combination columns in the axial compression process and the effects of different parameters were investigated, such as the concrete strength, stirrup ratio and confining index, on the axial compression properties of the combination columns, which provide relevant references and suggestions for practical engineering technology. The results of the research show that this new type of short combination columns is endowed with excellent axial compression properties.
